Explain how all echinoderms show five-sided radial symmetry when they look so different.

Answers

Answer 1

Sea cucumbers are echinoderms, a phylum that includes sea urchins and starfish.Echinoderms have a five-way radial symmetry, a pattern most familiar in the shape of the starfish.In sea cucumbers this character is shown in the five strips of muscle inside the body wall, running from the front to the back.The organism was motile and bilateral in symmetry. Bilateral symmetry means the organism can be cut right down the middle and be split into two equal halves. The echinoderm ancestry later developed radial symmetry as it was thought to be more advantageous to the species

2. Suppose that all possible n = 50 samples are selected from a population. How would the mean,
standard deviation, and shape of the resulting sampling distribution compare to a sampling
distribution based on all possible n= 100 samples?

Answers

Using the Central Limit Theorem, it is found that the mean and the shape would remain the same, while the standard deviation would be multiplied by the square root of 2.

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the sampling distribution is also approximately normal, as long as n is at least 30.

In this problem:

The sample size would remain above 30, hence the shape would still be normal.The mean does not depend on the sample size, hence it would remain constant.The standard deviation is inversely proportional to the square root of the sample size, then since the sample size would be divided by 2, the standard deviation would be multiplied by the square root of 2.
