Thirty randomly selected students took the calculus final. If the sample mean was 92 and the standard deviation was 9.4, construct a 99 percent confidence interval for the mean score of all students.
A) 87.29 < < 96.71 B) 87.77 < < 96.23 C) 89.08 < < 94.92 D) 87.27 < < 96.73

Suppose we have taken independent, random samples of sizes n1 = 8 and n2 = 8 from two normally distributed populations having means µ1 and µ2, and suppose we obtain , (something goes here but I cant type it) , s1 = 5, s2 = 4. Use critical values to test the null hypothesis H0: µ1 − µ2 < 20 versus the alternative hypothesis Ha: µ1 − µ2 > 20 by setting α equal to .10, .05,
