Use technology to find the P-value for the hypothesis test described below. The claim is that for 12 AM body temperatures, the mean is <98.6F. The sample size is n = 3 and the test statistic is t = -2.484. P-value= (Round to three decimal places as needed.) Use technology to find the P-value for the hypothesis test described below. The claim is that for the population of adult males, the mean platelet count is >209. The sample size is n = 58 and the test statistic is t = 1.329. P-value= (Round to three decimal places as needed.) Assume that a simple random sample has been selected and test the given claim. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. Use a 0.01 significance level. A data set includes platelet counts (1000 cells/L) measured from 169 adult males. In testing the claim that the population of adult males has a mean platelet count greater than 221, the accompanying technology display is obtained. Click the icon to view the technology display. Identify the null and alternative hypotheses for this test. A. Ho>221 (1000 cells/L) H = 221 (1000 cells/L) B. Ho H 221 (1000 cells/L) H: 221 (1000 cells/L) C.

Cholesterol levels were measured before and after the treatment. The changes (before minus after) in their levels of LDL cholesterol (in mg/dL) have a mean of 0.7 and a standard deviation of 19.3. Use a 0.01 significance level to test the claim that with garlic treatment, the mean change in LDL cholesterol is greater than 0. What do the results suggest about the effectiveness of the garlic treatment? Assume that a simple random sample has been selected.

Ho 0 mg/dL H: >0 mg/dL Assume that a simple random sample has been selected and test the given claim. Listed below are the lead concentrations in g/g measured in different traditional medicines. Use a 0.05 significance level to test the claim that the mean lead concentration for all such medicines is less than 14 g/g. 3.5 7.5 6.0 5.5 21.0 7.5 11.5 20.5 11.0 18.0 Identify the null and alternative hypotheses for this test.

Assume that a simple random sample has been selected from a normally distributed population and test the given claim. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. A safety administration conducted crash tests of child booster seats for cars. Listed below are results from those tests, with the measurements given in hic (standard head injury condition units). The safety requirement is that the hic measurement should be less than 1000 hic. Use a 0.05 significance level to test the claim that the sample is from a population with a mean less than 1000 hic. Do the results suggest that all of the child booster seats meet the specified requirement? 727 696 1176 632 534 483 Use technology to find the P-value for the hypothesis test described below.
