HW 10 hyp test: Problem 8 (1 point) A random sample of n = 7 observations from a normal population produced the following measurements: 7 4 7 8 2 10 Do the data provide sufficient evidence to indicate that o² < 3? Use a = 0.01, and compute the following: (a) sample standard deviation s = (b) test statistic x² (c) critical x The final conclusion is O A. We can reject the null hypothesis that o²: = 3 in favor of the alternative o² <3. O B. There is not sufficient evidence to reject the null hypothesis that o² ≥ 3.
