1) A manufacturer of cereal claims that the mean weight of a particular type of box of cereal is 1.2 pounds. A random sample of 71 boxes reveals a sample average of 1.186 pounds and a sample standard deviation of .117 pound. Using the .01 level of significance, is there evidence that the average weight of the boxes is different from 1.2 pounds?

Is the test statistic for this test Z or t?

Select one:

a. t

b. z

2) A manufacturer of cereal claims that the mean weight of a particular type of box of cereal is 1.2 pounds.

A producer of cereal measures part of its product quality by measuring box weight. It has established that each box should be 475 grams ± 5 grams. When the production was known to be under control, it obtained samples of 5 boxes and measured their weight. It then calculated the sample range R and sample mean x¯ (x bar). It then calculated the average of the ranges as R¯ = 5.5 grams and the average of the sample means as...
