Potato Bruises
A sample of 150 potatos were spot checked for bruises. "Yes" indicates that there were visible bruises.
Yes		To determine the total number of "Yes" answers, use =countif(select data in column A, "Yes")
Yes		To determine the total number of "No" answers, use =countif(select data in column A, "No")
Yes
Yes		x--the number of bruised potatos
Yes		n--sample size (total number of potatos checked)
Yes		point estimate (pbar)--x/n
Yes		z--use = - norm.s.inv((1-confidence level)/2)
Yes		standard error = sqrt(pbar*(1-pbar)/n)
Yes		margin of error = z*standard error
Yes		upper limit = pbar + margin of error
Yes		lower limit = pbar - margin of error

The produce manager for a large retail food chain is interested in estimating the percentage of potatoes that arrive on a shipment with bruises. A random sample of 150 potatoes was selected and spot checked for bruises. The data are in the file Potato Bruises.xlsx and should be used to answer the next several questions. Question 3 1/1 pts Determine the point estimate for the proportion of bruised potatoes in the shipment. Remember: when creating an interval to estimate the population proportion, the point estimate is the SAMPLE PROPORTION (pbar). Round to 4 decimal points. 0.0933 Question 4 1/1 pts Determine the critical value to be used in a 95% confidence interval for the proportion of bruised potatoes in the shipment. Round to 2 decimal places. Note: it is customary to list the positive critical value, even though a confidence interval will always contain a negative and a positive critical value (-z and z). 1.96 Incorrect Question 5 0/1 pts Determine the standard error for a 95% confidence interval for the proportion of bruised potatoes in the shipment. Round to 4 decimal places. Remember: when creating an interval to estimate the population proportion, the standard error is sqrt(pbar*(1-pbar)/n). 0.0777
