Correct option:
H0; = 35, H1: > 35, Test Statistic: Z = 7.25. P - value = 0.0001. Bcause the P - value is less than the significance level of 0.01, we reject the null hypothesis. There is sufficient evidence to support the claim that the true mean score for all sober subjcts is more than 35
Explanation:
H0; = 35, (the true mean score for all sober subjcts is not more than 35)
H1: > 35, (the true mean score for all sober subjcts is more than 35) (Claim)
Test Statistic is given by:
By Technology:
P- Value =0.0001
Since P- Value =0.0001 isless than = 0.01, the difference is significant. Reject null hypothesis.
Conclusion:
The data support the claim that the true mean score for all sober
subjcts is more than 35.

Identify the null hypothesis. alternative hypothesis, test statistic, decision about the null hypothesis and final conclusion that addresses the original claim Various temperature measurements are recorded at different times for a particular city. The mean of 20 degrees is obtained for 60 temperatures on 60 different days. Assuming that the population standard deviation is 1.5 degrees, test the claim that the population mean is 22 degrees. Use a 0.05 significance level Hou = 22; H1 is u# 22 Test statistic:...
Use a hypothesis test to test the given claim. A test of sobriety involves measuring the subject's motor skills. Twenty randomly selected sober subjects take the test and produce a mean score of 41.0 with a standard deviation of 3.4. At a significance level of 0.01, test the claim that the true mean score for all sober subjects is equal to 39.0. There is not enough information to perform the test. Fail to reject the null hypothesis of μ-39.0 with...

Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method. Use the normal distribution as an approximation of the binomial distribution. 7. In a recent poll of 745 randomly selected adults, 585 said that it is morally wrong to not report all income on tax returns. Use a 0.01 significance level report all income on tax returns. Identify the null hypothesis, altemative hypothesis, test...
Question 13 20 pts Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Various temperature measurements are recorded at different times during the summer in Holtville on n-60 days. The mean of 8 = 100°F is obtained, with 0 - 10°F. Using the 0.05 significance level, test the claim that the mean temperature is over 995 Hop-100; Hy w 100. Test statistic: 2-0.77. P-value: 0.7794. Because the...
Identify the null hypothesis, alternative hypothesis, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Test the claim about the population mean u at the level of significance a. Assume the population is normally distributed. Claim:us 45; a = 0.01; 0 = 4.3 Sample statistics: x = 46.8, n = 40 Fail to reject Ho. There is enough evidence at the 1% level of significance to support the claim. Reject Ho. There is enough evidence...
Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim In a study of 420,089 cell phone users, 120 subjects developed cancer of the brain or nervaus system. Test the claim af a somewhat common belief that such cancers are affected by cell phone use. That is, test the claim that cell phone users develop cancer of the brain or nervous system at a rate that is different...
Test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, and then state the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Among 2126 passenger cars in a particular region, 237 had only rear license plates. Among 304 commercial trucks, 45 had only rear license plates. A reasonable hypothesis is that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars....
Identify the null and alternative hypothesis, significance level, test that will be used, test statistic, P-value, conclusion about the null hypothesis, and state the final conclusion that addresses the original claim in nontechnical terms. In a clinical study of an allergy drug, 108 of the 202 subjects reported experiencing significant relief from their symptoms. At the 0.10 significance level, test the claim that more than half of all those using the drug experience relief.
Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method. Use either the T Calculator or the Normal Calculator to compute the P-value of the following test statistics. (a) The test statistic in a two-tailed is z = 1.39. Round to four decimal places. (b) Find the P-value for a right-tailed test with n = 27 and test statistic t = 1.502. Round to...
