Answer #1

When you perform a hypothesis test in statistics, a p-value helps you determine the significance of your results. A small p-value (typically ≤ 0.05) indicates strong evidence against the null hypothesis, so you reject the null hypothesis. Here in our case p value is 0.04 that means less than 0.05 , we reject the null hypothesis.

and when you construct the 95% confidence interval , it doesn’t include value 15.

    You set up a two-sided hypothesis test for a population mean μ with a null hypothesis of H0:μ=100. You chose a significance level of α=0.05. The p-value calculated from the data is 0.12, and hence you failed to reject the null hypothesis. Suppose that after your analysis was completed and published, an expert informed you that the true value of μ is 104. How would you describe the result of your analysis? A) A Type 1 error was made because...
