10. Lindsey purchased a random sample of 25 tomatoes at the farmers' market. The 95% confidence interval for the mean weight of the tomatoes is 90.6 grams to 112.4 grams.
(a) Find the point estimate and the margin of error.
Point estimate:
Margin of error:
(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.
(d) What would happen to the confidence interval if Lindsey changed to a 99% confidence
level?
(o) What would happen to the margin of error is Lindsey took a random sample of 175
tomatoes?
