7. A sociologist designs a test to measure prejudicial attitudes and claims that the mean population score is 60. The test is then
administered to 28 randomly selected subjects and the results produce a mean and standard deviation of 69 and 12 respectively. At the 5% level of significance, test the sociologist's claim.
please explain everything you did and what steps you did on your calculator to get the answer.

A sociologist develops a test to measure attitudes towards public transportation, and n = 81 randomly selected subjects are given the test. Their mean score is = 70.9 and their standard deviation is s = 16.5. Find the margin of error E for the 95% confidence interval for the mean score of all such subjects, and round to the nearest tenth.

A large software company gives job applicants a test of programming ability and the mean for that test has been 160 in the past. Twenty-five job applicants are randomly selected from one large university and they produce a mean score and standard deviation of 183 and 12, respectively. Use a 0.05 level of significance to test the claim that this sample comes from a population with a mean score greater than 160. Use the P-value method of testing hypotheses. A...

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...

An industrial company claims that the mean PH level of the water in a nearby river is 6.8. You randomly selected 16 water samples and measure the PH of each. The sample mean and standard deviation are 6.7 and 0.24, respectively. Is there enough evidence to reject the company's claim at 05? Assume the population is normally distributed. Set up appropriate hypotheses, calculate your test statistic, find the rejection region or P-value and make the final conclusion.

Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. A test of sobriety involves measuring the subject's motor skills. A study of n = 20 randomly selected sober subjects take the test and produce a mean score of X = 41.0, and we know that o = 3.7. At the 0.01 level of significance, test the claim that the true mean score for all sober subjects is...
