Test the claim that a place fills bottles with amounts having a mean less than 32 oz. A sample of 22 bottles produces a mean of 31.8 oz. and a population s. d. of 0.4 oz. What type of error could you have made in your decision? Use 1% significance level Please set up the null and alternate hypothesis and calculate the test statistic. Write the conclusion in terms of the problem.

2. A machine that fills beverage cans is supposed to put 12 ounces of beverage in each can. Following are the amounts measured in a simple random sample of eight cans. 11.96 12.10 12.04 12.13 11.98 12.05 11.91 12.03 A dotplot of the sample data suggests that the population is approximately normal. Perform a hypothesis test to determine whether the mean volume differs from 12 ounces. Use the a= 0.05 level of significance. (a) State the null and alternate hypotheses....

Let's now perform a mean-matched pairs test to test the claim that there is no mean difference between the age of males and females. For the context of this problem, d=x2−x1where the first data set represents actress (female) ages and the second data set represents male (actor) ages. We'll continue to use a significance of 0.05. You believe the population of difference scores is normally distributed, but you do not know the standard deviation. H0: μd=0 H1:μd≠0 Actress Age Actor...

Suppose you want to test the claim that the mean is less than or equal to 25.6. Given a sample size of n = 40 with sample standard deviation of 2, and a level of significance of alpha = 0.05, when would you reject the null hypothesis? Select one: a. Reject null if the test statistic is greater than 1.96. b. Reject null if the test statistic is greater than 2.021. c. Reject null if the test statistic is greater...

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:...
