The claim is that weights (grams) of quarters made after 1964 have a mean equal to 5.670 g as required by mintspecifications. The sample size is n = 37 and the test statistic is t = −2.706. Use technology to find the P-value. Basedon the result, what is the final conclusion? Use a significance level of 0.10.State the null and alternative hypotheses.Ho: μH₁:μ(Type integers or decimals. Do not round.)

A golf association requires that golf balls have a diameter that is 1.68 inches. To determine if golf balls conform to the standard, a random sample of golf balls was selected. Their diameters are shown in the aco data table. Do the golf balls conform to the standards? Use the a=0.05 level of significance. E Click the icon to view the data table. First determine the appropriate hypotheses. Hg: (Type integers or decimals. Do not round.) Find the test statistic. (Round to two decimal places as needed.) Find the P-value. (Round to three decimal places as needed.) What can be concluded from the hypothesis test? O A. Reject Hg. There is sufficient evidence to conclude that the golf balls do not conform to the association's standards at the a=0.05 level of significance. O B. Do not reject Hg. There is not sufficient evidence to conclude that the golf balls do not conform to the association's standards at the a 0.06 level of significance. OC. Do not reject Hg. There is sufficient evidence to…

Assume a significance level of a = 0.01 and use the given information to complete parts (a) and (b) below. Original claim: The mean pulse rate (in beats per minute) of a certain group of adult males is 68 bpm. The hypothesis test results in a P-value of 0.0061. O A. Reject H, because the P-value is less than or equal to a. O B. Fail to reject H, because the P-value is less than or equal to a. O C. Fail to reject Ho because the P-value is greater than a. O D. Reject H, because the P-value is greater than a. b. Without using technical terms, state a final conclusion that addresses the original claim. Which of the following is the correct conclusion? O A. There is not sufficient evidence to warrant rejection of the claim that the mean pulse rate (in beats per minute) of the group of adult males is 68 bpm. O B. The mean pulse rate (in beats per minute) of the group of adult males is not 68 bpm. O C. There is sufficient evidence to warrant rejection of the claim that the mean pulse rate (in…

Kenneth, a competitor in cup stacking, claims that his average stacking time is 8.2 seconds. During a practice session, Kenneth has a sample stacking time mean of 7.8 seconds based on 11 trials. At the 4% significance level, does the data provide sufficient evidence to conclude that Kenneth's mean stacking time is less than 8.2 seconds? Accept or reject the hypothesis given the sample data below. H0:μ=8.2 seconds; Ha:μ<8.2 seconds α=0.04 (significance level) z0=−1.75 p=0.0401 Select the correct answer below: a. Do not reject the null hypothesis because the p-value 0.0401 is greater than the significance level α=0.04. b. Reject the null hypothesis because the p-value 0.0401 is greater than the significance level α=0.04. c. Reject the null hypothesis because the value of z is negative. d. Reject the null hypothesis because |−1.75|>0.04. e. Do not reject the null hypothesis because |−1.75|>0.04.
