Get started for freeA company packages apples by weight. One of the weight grades is Class apples. Class apples have a mean weight of , and there is a maximum allowed weight tolerance of above or below the mean for apples in the same consumer package. A batch of apples is selected to be included in a Classapple package. Given the following apple weights of the batch, does the fruit comply with the Class grade weight tolerance requirements. Conduct an appropriate hypothesis test.
(a) at the significance level
(b) at the significance level Weights in selected apple batch (in grams): ; ; ; ;; ; ; ; 157 ; 171; 152; 161 ; 141; 166; 172;
According to an avid aquarist, the average number of fish in a -gallon tank is , with a standard deviation of two. His friend, also an aquarist, does not believe that the standard deviation is two.
