For each of the following confidence intervals, indicate how much of the distribution would be placed in the cutoff region for a two tailed test.
Suppose that the mean systolic blood pressure of healthy adults is normally distributed with a mean of 120 millimeters of mercury (mm Hg) and a standard deviation of 5.6 millimeters of mercury (mm Hg).
If the cutoffs for statistical test are -2.58 and 2.58, determine whether you would reject or fail to reject the null hypothesis in each of the following cases:
Supposing that the population is normally distributed, develop a 95% confidence interval estimate for the population mean for each of the following samples: Sample A: 1,1,1,1,8,8,8,8 Sample B: 1,2,3,4,5,6,7,8 Explain why these two samples produce

A radio show conducts a game according to the following rules. A number between 1 and 100 is selected at random, and the disc jockey announces what number is chosen. Call it n.
In general, the larger the value of the sample variance, the greater the likelihood of rejecting the null hypothesis.
