The standard error of fp computed in part (a) is 0.0352
The standard error of p computed in part (b) is 0.0352
It can be seen that standard error of \(\overline{p}\) is exactly the same in part (a) and part (b). Since the numerator of the formula of standard error of \(\overline{p}\) is p(1 — p) and whenever the value of p(1 — p) is same and the sample size is equal, the value of standard error will be the same.

The Wall Street Journal reported that the age at first startup for \(55\%\) of entrepreneurs was 29 years of age or less and the age at first startup for \(45\%\) of entrepreneurs was 30 years of age or more.
a. Suppose a sample of 200 entrepreneurs will be taken to learn about the most important qualities of entrepreneurs. Show the sampling distribution of \overline{p} where \overline{p} is the sample proportion of entrepreneurs whose first startup was at 29 years of age or less.
b. Suppose a sample of 200 entrepreneurs will be taken to learn about the most important qualities of entrepreneurs. Show the sampling distribution of \overline{p} where \overline{p} is now the sample proportion of entrepreneurs whose first startup was at 30 years of age or more.
c. Are the standard errors of the sampling distributions different in parts (a) and (b)?

The distribution of height for a certain population of women is approximately normal with mean 65 inches and standard deviation 3.5 inches. Consider two different random samples taken from the population, one of size 5 and one of size 85.
Which of the following is true about the sampling distributions of the sample mean for the two sample sizes?
Both distributions are approximately normal with mean 65 and standard deviation 3.5.
A
Both distributions are approximately normal. The mean and standard deviation for size 5 are both less than the mean and standard deviation for size 85.
B
Both distributions are approximately normal with the same mean. The standard deviation for size 5 is greater than that for size 85.
C
Only the distribution for size 85 is approximately normal. Both distributions have mean 65 and standard deviation 3.5.
D
Only the distribution for size 85 is approximately normal. The mean and standard deviation for size 5 are both less than the mean and standard deviation for size 85.
