Question

If, in a sample of n = 162 selected from a left skewed population, X = 64 and S = 19, would you use the test to test the null hypothesis H_0: mu = 59? Choose the correct answer below. A. Yes, you would use the t test because the sample size is at least 30 and this population size allows for the Central Limit Theorem to take effect. B. Yes, you would use the test because the sample size is at least 30 and this population size allows for the Central Limit Theorem to take effect. C. No, you would not used the test because the sample size is less than 30 and the population is left skewed. D. No you would not use the t test because the sample size is at least 30 and the population is left skewed.

Explanation / Answer

Option -2 is the answer

This is because we require normality for t-distribution which is satisfied by central limit theorem as sample size n>30.
