(Solved): 2nd/3rd blanks = Reject or Do not reject/ Insufficient or Sufficient. Question below. Thank you mi ...

minute. Complete parts (a) and (b) below. a. At the 0.05 level of significance, is there evidence that the population mean waiting time is different from 3.8 minutes?

Find $t$ p-val? $?d$ to three decimal places as needed.) State $?1$. $?=$ There is evidence to conclude that the population mean waiting time is different from 3.8 minutes. A. in is equal to 81 , the sampling distribution of the t test is approximately normal. In general, the t test is appropriate for this sample size unless the population is skewed. minute. Complete parts (a) and (b) below. a. At the 0.05 level of significance, is there evidence that the population mean waiting time is different from 3.8 minutes? State the null and alternative hypotheses. Determine the test statistic. The test statistic is (Round to two decimal places as needed.) Find the p-value. p-value $=($ Round to three decimal places as needed.$)$ State the conclusion. ${\mathrm{H}}_0$. There is evidence to conclude that the population mean waiting time is different from 3.8 minutes. B. Yes, because $\mathrm{n}$ is equal to 81 , the sampling distribution of the $t$ test cannot be determined. In general, the $t$ test requires a larger sample size. C. No, because $\mathrm{n}$ is equal to 81 , the sampling distribution of the $\mathrm{t}$ test is approximately normal. In general, the $\mathrm{t}$ test is appropriate for a large sample size.
