Seven of the 100 human genes that we sampled randomly from the human genome (in Example 4.1) were found to occur on the X chromosome. The sample fraction of genes on the X was thus p^ = 7/100=0.07 For each of the following statements, specify whether it is true or false:

a. p^=0.07  is the fraction of all human genes on the X chromosome.

b. p^=0.07 estimates p^p  the fraction of all human genes on the X chromosome.

c. p^ has a sampling distribution representing the frequency distribution of values of p^ that we might obtain when we randomly sample 100 genes from the human genome.

d. The fraction of all human genes on the X chromosome has a sampling distribution.

e. The standard deviation of the sampling distribution of p^  is the standard error of p^.
