(a) Find the point estimate and the margin of error. Point estimate: error: Margin of (b) Interpret the confidence level. (c) Based on the confidence interval, is it plausible that mean weight of all the tomatoes is less than 85 grams? Explain. (a) What would happen to the confidence interval if Lindsey changed to a 99% confidence level? (e) What would happen to the margin of error is Lindsey took a random sample of 175 tomatoes?
