In this example we will use the F test to check if the two population variances in Example 6.7 can be considered equal with a 95% confidence.

Data from Example 6.7

A certain product of organic beans are packed in tins and sold by two local shops. The local authority have received complaints from customers that the amount of beans within the tins sold by the shop are different. To test this statistically two small random samples were collected from both shops. Conduct a two sample t-test for the population mean (independent samples, equal variance) to test this hypothesis.
