We obtain a sample of size = 18 and find that x= 73 and s = 3. We hypothesize that mean = 71. Does this claim seem reasonable? Assume a normal distribution. Answer this question by performing the following steps. Part 1: a) Find t b) Part 2: b) The middle 95% of values from the t-Distribution lie in the interval [(-t)0.025 , (t)0.025] . Find these values. (-t)0.025(n-1) = (rounded to 3 decimals) (t)0.025(n-1) = (rounded to 3 decimals)
