Question 4 There are hundreds of apples on the trees, so you randomly choose just 79 apples and get a mean weight of 82.95 grams with a standard deviation of 6.81 grams. Assuming that the weight of the apples is normally distributed, what is the lower bound of the 90% confidence interval for the mean weight of the apples. Note: Round your answers to 4 decimal places.
