Solve for D)
Transcribed Image Text:In an advertising campaign, a snack company claimed that every 18-ounce bag of its cookies contained at least 1000 chocolate chips. Two statisticians attempted to verify the claim. The accompanying
data represent the number of chips in an 18-ounce bag of the company's cookies based on their study. Complete parts (a) through (e)

The standard deviation of the sample data is 101.6
(Round to one decimal place as needed)
(c) Using the sample mean and sample standard deviation obtained in part (b) as estimates for the population mean and population standard deviation, respectively, draw a graph of a normal model
for the distribution of chips in a bag of cookies.
