A major grocery store chain is trying to cut down on waste. Currently, they get peaches from two different distributors, WholeFruits and GreenGrocer. Out of a two large shipments, the manager randomly selects items from both suppliers and counts the number of items that are not sell-able due to bruising, disease or other problems. She then makes a confidence interval. Is there a significant difference in the quality of the peaches between the two distributors? 95% CI for pW-pG:(-0.156, 0.064)

Explain
A major grocery store chain is trying to cut down on waste. Currently, they get peaches from two
different distributors, WholeFruits and GreenGrocer. Out of a two large shipments, the manager
randomly selects items from both suppliers and counts the number of items that are not sell-able
due to bruising, disease or other problems. She then makes a confidence interval. Is there a
significant difference in the quality of the peaches between the two distributors?
95% CI for pW-pG:(-0.156, 0.064)
We are 95% confident that the proportion of non sell-able peaches from Whole Fruits is anywhere between
0.064 and 0.156.
O We are 95% confident that the proportion of non sell-able items for Whole Fruits is anywhere between
0.156 LOWER and 0.064 HIGHER than the proportion of non sell-able items for Green Grocer.
O We are 95% confident that the proportion of non sell-able peaches for Whole Fruits is about -0.064 and
0.156.
We are 95% confident that the proportion of non sell-able items for Whole Fruits is anywhere between
0.064 and 0.156 HIGHER than the proportion of non sell-able items for Green Grocer.
O We are 95% confident that the proportion of non sell-able items for Whole Fruits is anywhere between
0.064 and 0.156 LOWER than the proportion of non sell-able items for Green Grocer.
