An agronomist would like to estimate the average weight of all Indian River County grapefruits. The mean weight of a random sample of 100 Indian River County grapefruits was found to be 201 grams. The standard deviation of the weights of all Indian River County grapefruit is known to be 14 grams. Find three different confidence intervals one with a 98% confidence level, one with a 97% confidence level, and one with a 96% confidence level for the mean weight of all Indian River County grapefruits . Notice how the confidence level affects the margin of error and the width of the interval. Report confidence interval solutions using interval notation. Round solutions to two decimal places, if necessary.
