An agronomist would like to estimate the average weight of all Indian River County grapefruits. The mean weight of a random sample of 200 Indian River County grapefruits was found to be 236 grams. The standard deviation of the weights of all Indian River County grapefruit is known to be 10 grams. Find three different confidence intervals one with a 99% confidence level, one with a 98% confidence level, and one with a 97% 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.

An agronomist would like to estimate the average weight of all Indian River County grapefruits. The mean
weight of a random sample of 200 Indian River County grapefruits was found to be 236 grams. The standard
deviation of the weights of all Indian River County grapefruit is known to be 10 grams.
Find three different confidence intervals - one with a 99% confidence level, one with a 98% confidence
level, and one with a 97% 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.
