The Ericsson method is one of several methods claimed to increase the likelihood of a baby girl. In a clinical trial, results could be analyzed with a formal hypothesis test with the alternative hypothesis of p>0.5, which corresponds to the claim that the method increases the likelihood of having a girl, so that the proportion of girls is greater than 0.5. If you have an interest in establishing the success of the method, which of the following P-values would you prefer: 0.999, 0.5, 0.95, 0.05, 0.01, 0.001? Why? The P-value of (0.999.05.095.005-001.0001) 2 is preferred because it corresponds to the sample evidence that most strongly supports the (null/ altenative)? hypothesis that the method (is/ is not)? effective.
Answer:
0.001
Step-by-step explanation:
Ericsson is claimed to increase the likelihood of a baby girl ;
Given the alternative hypothesis to buttress this claim :
HA : p>0.5
In other to establish the success of Ericsson's claim, then there must be significant evidence to reject the Null hypothesis ; hence adopt the alternative.
To Do this, we need a very small Pvalue ; such that it will be lesser than the α - value in other to reject the Null and adopt the alternative.
Recall ;
Pvalue < α ; We reject the Null
Therefore, from the options, we choose the smallest Pvalue as we want the Pvalue to be as small as possible.

yall i have exams tomorrow and i have no clue how to do percentages TwT helppp
Answer:
24 is 44% of 54.55
Step-by-step explanation:
24 ÷ 44% = y ÷ 100%
Solve for y - To do so, we will use cross multiplication.
44y = 24 × 100
44y = 2400
y = 2400 ÷ 100
y = 54.55

Step-by-step explanation:
mC = 180 - 46 - 105 = 29
By Law of Sines: c/sin C = a/sin A
19.8/sin 29° = a / sin 46°
19.8/0.484 = a/0.72

Use the distributive property to remove the parentheses.
- 4(5u - 3y-1)
Answer:
-20u + 12y + 4
Step-by-step explanation:
We have the equation -4(5u - 3y - 1) and are asked to use the distributive property to remove the parenthesis.
When using the distributive property, you have to multiply the number outside the parenthesis to all numbers inside the parenthesis, do as followed :
-4(5u - 3y - 1)
(5u(-4) -3y(-4) -1(-4))
-20u + 12y + 4

Answer:
600
Step-by-step explanation:
Well, first you need to make a proportion which will be [tex]\frac{x}{6,000} = \frac{10}{100}[/tex]
x is what we need to find
6,000 is the total people who voted
10% is the percent of 18 to 29 years old
and 100% represents the circle graph because all circle graphs equal 100%
First, we use the cross multiply method, for instance, 6,000×10=60,000
Next, divide 60,000÷100 which is 600.
Therefore there are 600, 18 to 29 year olds who voted in the election.
Irene knows there are 2 cups in 1 pint. She writes the equation c=2p to find the number of cups, c, in any number of pints, p. Use the drop-down menus to complete the statements about Irene's equation.
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as there are no options to select from.
However, a general explanation is as follows.
Given
[tex]2\ cups = 1\ pint[/tex]
Required
Is [tex]c = 2p[/tex] a correct expression?
Let
[tex]c = cups[/tex]
[tex]p = pint[/tex]
So:
[tex]2\ cups = 1\ pint[/tex]
becomes
[tex]2 * c = 1 * p[/tex]
[tex]2c = p[/tex]
Divide both sides by 2
[tex]c =\frac{1}{2}p[/tex]
Hence:
[tex]c = 2p[/tex] is incorrect

Min has a shelf filled with books. The books have different thicknesses. This line plot shows the thickness of each book. He piles the four thickest books on top of each other. How thick is the pile?
Answer:
[tex]$2\frac{1}{4} \ inch$[/tex]
Step-by-step explanation:
We have the four thickest books from the line plot given by
Two books of [tex]$\frac{1}{2}$[/tex] inch thick and the two books of [tex]$\frac{5}{8}$[/tex] inch thickness.
So when the two [tex]$\frac{1}{2}$[/tex] inch thick book is being piled on the top of a [tex]$\frac{5}{8}$[/tex] inch thick books.
Therefore, the total thickness of the pile of books is given by :
[tex]$=2 \times \frac{1}{2}+2 \times \frac{5}{8}$[/tex]
[tex]$=\frac{9}{4}$[/tex]
[tex]$=2\frac{1}{4} \ inch$[/tex]
Therefore, the thickness of the pile is [tex]$2\frac{1}{4} \ inch$[/tex] .
The addition is one of the four fundamental mathematical operations. The thickness of the pile is 4.75 inches.
What is Addition?The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.
As per the given graph, the top four thickest books are:
2 books of thickness 1 1/8 inches2 books of thickness 1 1/4 inchesTherefore, the thickness of the pile is the sum of the thickness of the four books.
[tex]\text{The thickness of pile} = 1\frac18 +1\frac18 + 1\frac14 + 1\frac14\\[/tex]
[tex]= \dfrac98 +\dfrac98 + \dfrac54 + \dfrac54\\\\= 4.75[/tex]
Hence, the thickness of the pile is 4.75 inches.

Brianna's teacher asks her which of these three expressions are equivalent to each other. which is equivalent
Answer:
Please specify what the three expressions are.
Step-by-step explanation:
From what I understand, you need to set the expressions equal to each other. For instance, if one is 2(x-3) and the other is 2x-6, you could write it as:
[tex]2(x-3)=2x-6[/tex]
Then, by evaluating it, you would get:
[tex]2x-6=2x-6[/tex] by distribution over subtraction.
[tex]2x-6+6=2x-6+6[/tex] by the additive property of equality
[tex]2x=2x[/tex] Simplify.
[tex]x=x[/tex] by the reflexive axiom.
Since x will always equal itself, 2(x-3) and 2x-6 are equivalent.
Therefore, if the expressions, once set equal to each other, result in the equation x=x, or any other expression in which one quantity equals itself, the two expressions are equal.
Sorry I could not be of more help, but you did not specify what the expressions were.

A business has a savings account that earns a 3% annual interest rate. At the end of 1996, the business had $4,000 in the account. The formula
F = p (1+r/100)
t is used to determine the amount in the savings account.
F is the final amount,
p is the initial investment amount,
r is the annual interest rate, and
t is the time in years.
To the nearest dollar, how much did the business initially invest in 1991?
A. $3,450
B. $3,455
C. $4,631
D. $4,637
Answer:
The amount the business initially invested in 1991 is approximately;
A. $3,450
Step-by-step explanation:
The question relates to investment and finance
The parameters given are;
The annual interest rate on the business savings account = 3%
The amount the business had in the account at the end of 1996 = $4,000
The given formula used to determine the final amount in the savings account, [tex]F = p \cdot \left(1 + \dfrac{r}{100} \right )^t[/tex]
Where;
F = The final amount
p = The initial (principal) investment
r = The annual interest rate
t = The time in years
Therefore, we have;
The required information = The initial amount, 'p', the business invested in 1991
The time in years, 't', from 1991 to 1996 = 1996 - 1991 = 5
∴ The time in years from 1991 to 1996, t = 5 years
The final amount in 1996, F = $4,000
r = 3%
Plugging in the values in the given equation gives;
[tex]4000 = p\cdot \left(1 + \dfrac{3}{100} \right )^5[/tex]
Therefore;
[tex]p = \dfrac{4000}{\left(1 + \dfrac{3}{100} \right )^5} = 3,450.43513754[/tex]
To the nearest dollar, the initial amount the business invested in 1991, p ≈ $3,450.
