Question 5 1 point Determine whether the hypothesis test inv

Question 5 (1 point) Determine whether the hypothesis test involves a sampling distribution of means that is a normal distribution (z), Student t distribution, or neither. Claim: population mean 102. sample data: n 13, x-bar 103, s 15.1. The sample data appear to come from a normally distributed population with unknown mean and unknown sigma. O a) Normal z O b) Student t c) Chi-square O d) Neither Save

Solution

The correct answer is Option B, student-t distribution

Reason: Since the number of samples are equal to 13, which are very less and student-t test is used on smaller sample size for which the value of n is less than or equal to 50
