Question

The measure of the hemoglobin MC levels is indicative or how high glucose eve1s have been maintained for the past several months. A in medical laboratory, in trying to find out what is the range of A1C values tot Its patient population, randomly selects 500 patients and determines their hemoglobin MC levels. The laboratory obtains an average value of 4.8. The standard deviation is 0.4. Using the table given, how many of these patients are termed as having normal glucose levels?

Answer 1

Total patients = 500

% of normal patients =( 4 - 5.3) %

Solution

when 4%

number of patients = 4%(500) =20

when 4.1

numbe of patients = 20.5

when 4.2

number of patients = 21

when 4.3

number of patient = 21.5

when 4.4

number of patients =22

when 4.5

numbe of patients = 22.5

when 4.6

number of patients = 23

when 4.7

number of patients = 23.5

when 4.8

number of patients = 24

when 4.9

number of patients = 24.5

when 5

number of patients = 25

when 5.1

number of patients = 25.5

when 5.2

number of patients = 26

when 5.3

number of patients = 26.5

Average normal glucose level patients = 20.5+21+21.5+22+22.5+23+23.5+24+24.5+25+25.5+26+26.5 / 13

= 23.5
