In general, for a confidence interval constructed to estimate the population proportion, p, holding all else equal, which confidence level would produce the widest confidence interval?

Is there a significant difference in prices between a 0.99 carat diamond and a 1 carat diamond? Two random samples of diamonds, one sample of 0.99 carat diamonds and one sample of 1 carat diamonds, were collected and their price was recorded. The statistics from these samples is presented in the table below.    Statistics 0.99 Carats 1 Carat Mean $4,406 $5,601 Standard Deviation $1,302 $1,613 Sample Size 23 23   Calculate the estimate of parameter being tested (i.e. the sample statistic calculated from the data).

The statistics from these samples is presented in the table below.    Statistics 0.99 Carats 1 Carat Mean $4,406 $5,601 Standard Deviation $1,302 $1,613 Sample Size 23 23   Given the p-value for this test is 0.014 and using a significance level of 0.05, what decision can you make? Provide a reason for this decision.

Suppose that a 90% confidence interval for estimating the difference of the population means ()  is found to be (-5.14, 0.54). Which of the following is most likely the p-value for the randomization hypothesis test of H0:  = 0 vs. Ha: ≠ 0?

In general, if a decision was made to reject the null hypothesis, one can conclude that
