esearcher wants to determine if there is a significant difference between the average weight of two different types of apples, Red Delicious and Granny Smith. They collect a sample of 25 Red Delicious apples and weigh each one, finding a mean weight of x̄1 = 170g and a standard deviation of s1 = 15g. They also collect a sample of 30 Granny Smith apples and weigh each one, finding a mean weight of x̄2 = 165g and a standard deviation of s2 = 20g. At a significance level of α = 0.05, perform a two-sample t-test to determine if there is a significant difference in the average weight of the two types of apples
