Test the claim about the population mean μ at the level of significance α. Assume the population is normally distributed. Claim: μ< 4915; x = 0.02 Sample statistics: x= 5017, s=5613, n=54 What are the null and alternative hypotheses? Ho H > 4915 Ha: H < 4915 Type integers or decimals. Do not round.) Find the standardized test statistic t. Round to two decimal places as needed.)

Use technology to help you test the claim about the population mean, µ, at the given level of significance, a, using the given sample statistics. Assume the population is normally distributed. Claim: µ> 1170; a = 0.07; o = 212.01. Sample statistics: x= 1185.03, n= 300 Identify the null and alternative hypotheses. Choose the correct answer below. Ο Α. Ho μ2 1185.03 Ο Β. Ho : με 1185.03 Ha: µ 1185.03 O C. H μ2 1170 O D. Ho: µ> 1170 Ha: H 1185.03 Ha: µ> 1170 Ha: us1185.03 Calculate the standardized test statistic. The standardized test statistic is (Round to two decimal places as needed.) Determine the P-value. P = (Round to three decimal places as needed.) Determine the outcome and conclusion of the test. Ho. At the 7% significance level, there enough evidence to the claim.

Listed below are systolic blood pressure measurements (mm Hg) taken from the right and left arms of the same woman. Assume that the paired sample data is a simple random sample and that the differences have a distribution that is approximately normal. Use a 0.10 significance level to test for a difference between the measurements from the two arms. What can be concluded? Right arm 142 132 127 137 130 D Left arm 174 172 184 137 147 O A. Ho: Hd =0 B. Ho: Ha 0 H1: Hd =0 %3D OC. Ho: Hd = 0 H1: Hd 0 Identify the test statistic. (Round to two decimal places as needed.) t= Identify the P-value. P-value = (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test?

A sample​ mean, sample​ size, and sample standard deviation are provided below. Use the​ one-mean t-test to perform the required hypothesis test at the 10​% significance level.   x=25​, s=10​, n=24​, H0​: μ=24​, Ha​: μ>24   The test statistic is t= (round to two decimals as needed)

identify the test statistic. Identify the​ P-value.

Decide whether the normal sampling distribution can be used. If it can be​ used, test the claim about the difference between two population proportions p1 and p2 at the given level of significance α using the given sample statistics. Assume the sample statistics are from independent random samples.   ​Claim: p1=p2​, α=0.10 Sample​ statistics: x1=142​, n1=156 and x2=144​, n2=188 Find the standardized test statistic. Select the correct choice below​ and, if​ necessary, fill in the answer box to complete your choice.
