Bags of a different type of potato chip claim to have a net weight of 14 ounces. I purchase a random sample of 10 bags from stores around Tucson. I find a sample mean of x = 13.86 ounces, and a sample standard deviation of s = 0.23 ounces.

1.) Compute the critical value for a 95% confidence interval assuming all conditions are valid. Report the positive critical value rounded to 3 decimal places.

2.) Compute the margin of error for a 95% confidence interval assuming all conditions are valid. Round to 3 decimal places.

Then based on the interval in the previous problem, would you support or reject a claim that population mean weight is 14 ounces?

options:

A Support the claim, because the claimed value lies inside the confidence interval.

B Reject the claim, because the claimed value lies inside the confidence interval.

C Support the claim, because the claimed value lies outside the confidence interval.

D Reject the claim, because the claimed value lies outside the confidence interval.
