Manufacturers of Ben & Jerry's Ice Cream would like to check the quality of their batches of Cherry Garcia, their most popular ice cream flavor. Since they have recently been receiving complaints from customers claiming that there aren't enough cherries in their pints of Cherry Garcia, the company would like to evaluate whether their recent batches contain fewer cherries than their known average 27 cherries. Below are the numbers of cherries the company has counted in 9 pints they have manufactured from their most recent batch.  Test this hypothesis using an alpha level of .01.

x: {19, 24, 22, 20, 26, 26, 21, 28, 19]

Answer 1

Claim: Recent batches contain fewer cherries than their known average 27 cherries.

The null and alternative hypothesis is:

H0 :μ2 27

H1 :μ< 27

Level of significance = 0.01

By using SPSS we have to solve this question:

Enter data into SPSS software.

We get

Test statistic = t = -3.786

P-value = P(T < -3.786) = 0.0027

P-value < 0.01 we reject null hypothesis.

Conclusion:

Recent batches contain fewer cherries than their known average 27 cherries.
