For a randomly selected data, the 90% confidence interval limits for the population mean are between 170.86 and 195.42. If the 10% level of significance were used in testing the hypotheses H?: m = 201 vs. H?: m ? 201, the null hypothesis: would be accepted. would fail to be rejected. would become H?: m ? 201 would be rejected. None of the suggested answers are correct

For a randomly selected data, the 90% confidence interval limits for the population mean are between 170.86 and 195.42. If the 10% level of significance were used in testing the hypotheses H0: μ = 201 vs. H1: μ ≠ 201, the null hypothesis: a. would be accepted. b. would become H0: μ ≠ 201 c. would fail to be rejected. d. None of the suggested answers are correct e. would be rejected.

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.

To test $H_{0}: \mu=45$ versus $H_{1}: \mu \neq 45,$ a simple random sample of size $n=40$ is obtained. (a) Does the population have to be normally distributed to test this hypothesis by using the methods presented in this section? Why? (b) If $\bar{x}=48.3$ and $s=8.5,$ compute the test statistic. (c) Draw a $t$ -distribution with the area that represents the $P$ -value shaded. (d) Determine and interpret the $P$ -value. (c) If the researcher decides to test this hypothesis at the $\alpha=0.01$ level of significance, will the researcher reject the null hypothesis? Why? (f) Construct a $99 \%$ confidence interval to test the hypothesis.
