(a)
To check the assumptions and conditions for inference.
(a)
Explanation of Solution
We have to check the conditions for inference for the following data provided in the question. Thus, now we will check the same as:
Random condition: It is satisfied because the bags were randomly selected.
Independent condition: It is satisfied because since the sample of
Normal condition: It is satisfied because the histogram shows no outlier and the normal quantile plot is nearly normal.
Thus, all conditions and assumptions of the inference are met.

Answer to Problem 36E
The confidence interval is
Explanation of Solution
It is given:
Thus, the mean of the data given in the question is:
The standard deviation of the data given is as:
The degrees of freedom is:
Thus, the t -value is:
Therefore the confidence interval is:
Thus, the confidence interval is
