The American Diabetes Association recommends a blood glucose reading of less than 130 for those with Type 2 diabetes. Blood glucose measures the amount of sugar in the blood. Below are the readings for February for a person recently diagnosed with Type 2 diabetes.

102 126 113 97 112 126 109 105 124 110
105 96 106 117 126 106 123 109 114 99

Answer #1

Here, we have given that

X: Blood glucose reading less than 130 for those persons with type 2 diabetes.

X (Blood Glucose Reading)

n=number of observations =28

(A)Now, we want to find the arithmetic mean of glucose reading

=110.68

average =110.68

(B)

Now, we want to find the median

we know that, here we have total 28 observation means it is event number

then median is the average of the middle two number after sorting of the data (X)
Median = 109+109/2 =109

Median =109

(C)

Here,

109 value of glucose reading occur 5 times and also 114,113 occur two time which make this model as Bi-model.

A fast-food franchiser is considering building a restaurant at a certain location. Based on financial analyses, a site is acceptable only if the number of pedestrians passing the location averages more than 100 per hour. The number of pedestrians observed for each of 40 hours was recorded. Assuming that the population standard deviation is known to be 16, Estimate with 95% confidence the mean number of pedestrians passing the location. Can we conclude at the 5% significance level that the...

A digital blood pressure gauge is under fire for its inaccuracy, so the medical association has selected a group of 15 patients. They were asked to have their (systolic) blood pressure taken first by an accredited physician (with accurate readings of systolic pressure), and then to go home and use the digital blood pressure gauge themselves. The data for the 15 patients tested: Patient Physician Gauge A 112 126 B 109 108 C 139 116 D 141 123 E 120...
