Two-tail Chi-square Test of Variance
A company packages apples by weight. One of the weight grades is Class A apples. Class A apples have a mean weight of 150 g, and there is a maximum allowed weight tolerance of 5% above or below the mean for apples in the same consumer package. A batch of apples is selected to be included in a Class A apple package. Given the following apple weights of the batch, does the fruit comply with the Class A grade weight t22olerance requirements? Conduct an appropriate hypothesis test at the 5% and 1% significance level s. The weights in the selected apple batch (in grams) follow:
158; 167; 149; 169; 164; 139; 154; 150; 157; 171; 152; 161; 141; 166; 172.
