Question

Harold took five different samples of thirty-five randomly selected students from the 520 students he surveyed. The means of the samples are shown below. Sample Mean Sample 1 3.4 Sample 2 3.2 Sample 3 4.1 Sample 4 4.6 Sample 5 3.1 The predicted mean of the population will fall between 3.1 and _______. 1.5 3.4 3.7 4.6

Answer 1

D 4.6

Step-by-step explanation:

Answer 2

Answer: d)In repeated samples of the same size, approximately 95 percent of the intervals constructed from the samples will capture the population difference in means.

Step-by-step explanation:

If we construct 100 of the given confidence interval, we are confident that 95% of them would contain the true population parameter. Therefore, the correct option is

d)In repeated samples of the same size, approximately 95 percent of the intervals constructed from the samples will capture the population difference in means.
