Distributions Identify the distribution (normal, Student t, chi-square) that applies toeach of the following situations. (If none of the three distributions is appropriate, thenso state.)a. In constructing a confidence interval of m, you have 50 sample values and they appearto be from a population with a skewed distribution. The population standard deviation isnot known. b. In constructing a confidence interval estimate of m, you have 50 sample values and theyappear to be from a population with a skewed distribution. The population standard deviationis known to be 18.2 cm.c. In constructing a confidence interval estimate of s, you have 50 sample values and theyappear to be from a population with a skewed distribution.d. In constructing a confidence interval estimate of s, you have 50 sample values and theyappear 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.
