Meth Barie's ice cream shop wants to decide whether to introduce a new ice cream flavor. They randomly selected 15 customers at their downtown Denton location to rate this new flavor. The rating is on a scale of 1 to 5, with 1 being 'not interested' and 5 being 'strongly interested'. Meth Barie's will approve the new flavor if the true mean rating is over 4.0. What is the rejection region for testing at the 0.1 level of significance?

Data on the weights (lb) of the contents of cans of diet soda versus the contents of cans of the regular version of the soda is summarized to the right. Assume that the two samples are independent simple random samples selected from normally distributed populations, and do not assume that the population standard deviations are equal. Complete parts (a) and (b) below. Use a 0.05 significance level for both parts. a) Test the claim that the contents of cans of diet soda have weights with a mean that is less than the mean for the regular soda. What are the null and alternative hypotheses? The test statistic, t, is_____.(Round to two decimal places as needed.) The P-value is____. (Round to three decimal places as needed.) State the conclusion for the test. A. Fail to reject the null hypothesis. There is not sufficient evidence to support the claim that the cans of diet soda have mean weights that are lower than the mean weight for the regular soda. B. Reject the null…

Making auto parts A grinding machine in an auto parts plant prepares axles with a target diameter 40.125 millimeters (mm). The machine has some variability, so the standard deviation of the diameters is o = 0.002 mm. The machine operator inspects a random sample of 4 axles each hour for quality control purposes and records the sample mean diameter r. Assuming that the process is working properly, what are the mean and standard deviation of the sampling distribution of x? Explain. Making auto parts Refer to Exercise 50. How many axles would you need to sample if you wanted the standard deviation of the sampling distribution of x to be 0.0005 mm? Justity your answer.
