4. Blood Glucose Level. A research explored the relationship between students who skip breakfastand their performance on a number of cognitive tasks. According to the findings, blood glucose ( i)i ) levels in the morning, after a 9-hour fast, have a mean of 4.60 mmol/L with a standarddeviation of 0.16 mmol/L.(a) Determine the sample distribution of the sample mean for samples of size 60. (What is thesampling distribution? What are the mean and standard deviation for this distribution?) 10%(b) Must you assume that the blood glucose levels are normally distributed to answer part (a)?Explain why.10%
