# Question: Identify the distribution normal Student t chi square that applies to

Identify the distribution (normal, Student t, chi-square) that applies to each of the following situations. (If none of the three distributions is appropriate, then so state.)
a. In constructing a confidence interval of m, you have 50 sample values and they appear to be from population with a skewed distribution. The population standard deviation is not known.
b. In constructing a confidence interval estimate of m, you have 50 sample values and they appear to be from a population with a skewed distribution. The population standard deviation is known to be 18.2 cm.
c. In constructing a confidence interval estimate of s, you have 50 sample values and they appear to be from a population with a skewed distribution.
d. In constructing a confidence interval estimate of s, you have 50 sample values and they appear to be from a population with a normal distribution.
e. In constructing a confidence interval estimate of p, you have 850 survey responses and 10% of them answered “yes” to the first question.
