Assume that a 99% confidence interval for the mean is 17.0 < u < 19.0. The null hypothesis H0: U = 16.0, α = 0.01 would not be rejected because 19.0 is more than 17.0. It would not be rejected because 16.0 is less than 19.0. It would be rejected because 16.0 is not equal to 18.0. It would be rejected because 16.0 is less than 17.0.

Step 1
0. The 99% confidence interval for the mean is 17.0 < μ < 19.0. Since the null hypothesis value of 16.0 is not within the confidence interval, we reject the null hypothesis. ** Show more…

Based on the sample data, the 90% confidence interval limits for the population mean are LCL = 170.86 and UCL = 195.42. If the 10% level of significance were used in testing the hypotheses H0: μ = 201 vs. H1: μ ≠201, the null hypothesis would be rejected.

Based on the following results, conclude whether to reject or not reject H0. H0: p = 0.75; Ha: p > 0.75 α = 0.05 (significance level) The test statistic is 2.59. The critical value is z0.05 = 1.65. Select two responses below. Reject H0. Fail to reject H0. The test statistic falls within the rejection region. The test statistic is NOT in the rejection region.

Estimate the minimum sample size needed to form a confidence interval for the mean of a population having the standard deviation shown, meeting the criteria given. a. $\quad \sigma=4,95 \%$ confidence, $E=1$ b. $\quad \sigma=4,99 \%$ confidence, $E=1$ c. $\quad \sigma=4,95 \%$ confidence, $E=0.5$
