O Macmillan Learning One important test for kidney disease involves measuring the levels of bicarbonate (HCO,) in blood. Normal bicarbonate levels for a person ranging in age from 18 to 59 years old is 23-29 mmol/L. A lab purchased a new instrument to measure bicarbonate levels in blood and needs to certify it against their current instrument. The bicarbonate levels in the blood of a 38 year old woman was measured using the old and new instrument. The blood was tested 6 times using each instrument. The mean concentration of bicarbonate using the old instrument was found to be 24.4 mmol/L. with a standard deviation of 1.54 mmol/L. The new instrument yielded a mean concentration of 25.5 mmol/L with a standard deviation of 0.48 mmol/L... Determine if there is a significant difference in the standard deviations of the two sets of measurements made by the two instruments at the 95% confidence level. Determine the value of Fale Feate= 10.293 Determine the value of Fuble- Refer to the table of critical values of F as needed. Fable 4.39 incorrect
