A machine that is used to fill soda pop cans with pop has an adjustable mean fill setting, but the standard deviation is not supposed to exceed 0.18 ounces.
To make sure that this is the case, the managers at the beverage company each day select a random sample of n = 6 cans and measure the fill volume carefully. In one such case, the following data (ounces per can) were observed.12.29 11.88 12.03 12.22 11.76 11.98Based on these sample data, the test statistic is approximately 2 = 5.01. Indicate whether the statement is true or false
Question 2
A large Midwestern university is interested in estimating the mean time that students spend at the student recreation center per week. A previous study indicated that the standard deviation in time is about 40 minutes per week.
If the officials wish to estimate the mean time within 10 minutes with a 90 percent confidence, what should the sample size be?A) 44
B) 62
C) 302
D) Can't be determined without knowing how many students there are at the university.
