The following scenarios each contain enough information to carry out a hypothesis test for means. For each one, (1) give the formula for the test statistic (in terms of the variables, not the numbers in the problem!), (2) indicate which distribution you would use to determine the critical value, and (3) give the number of degrees of freedom, either as a formula or as calculated for the problem (if relevant). You don’t have to explain your answers, and you don’t...

A hypothesis test with a 5% level of significance is designed to test the claim that the mean weight of a new breed of chickens is greater than 6.00 pounds. A sample of 81 chickens is obtained and their mean weight is 6.20 pounds with a sample standard deviation of 0.50 pounds. No information is available concerning the standard deviation of the whole population of the new breed. What is the critical value (from Table A-3) and the test statistic...

Suppose that you wish to use a hypothesis test to test a claim made by a juice bottling company regarding the mean amount of juice in its 16 oz bottles. The company claims that the mean amount of juice in its 16 oz bottles is 16 oz, while you suspect the true mean is lower. You obtain n = 15 bottles of juice and find a sample mean of x¯ = 15.42 oz with a sample standard deviation of s...
