Question

30 is 0.037. Does the 95% 3. (1 pt) The p-value for a two-sided test of the null hypothesis Ho: confidence interval include the value 30? Explain.

Answer 1

We have , the p-value for the two tailed test is 0.037

The significance level is

= 0,05

Decision : by using p-value ,

p-value=0.037<

= 0,05

Therefore , reject Ho.

Also , the decision by using confidence interval : If the hypothesized value of $\mu_0$ does not lies in the confidence interval, then reject Ho.

Here , our decision by using p-value is reject Ho

Therefore , the value 30 does not lies in the confidence interval. Because we rejecting the null hypothesis.
