You are the product manager for Joe Totter Supermarket. You are interested in validating the contents of the one-pound bags of Keen potato chips. You select a random sample of 9 bags and empty the contents of each bag, one at a time, onto a scale and record the weights in pounds. Below are the recorded sample weights: 1.11.21.00.91.11.31.21.1

Assuming the weights of potato chips are normally distributed, estimate the mean weight of a bag of Keen potato chips using a 95% confidence interval.

Hence, the mean of the potato chips lie between the interval

Given :

data is :

Confidence level is .

To find :

Confidence interval.

Explanation :

Mean

Standard deviation

here,

by the Z- table

confidence interval is :

Therefore, the mean of the potato chips lie between the interval

answer: yes youre right.

step-by-step explanation:

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
