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 Feale= 10.293 Determine the value of Fuble- Refer to the table…

Mass of sample = 0.2492g Number of insects = 6 Initial watch glass weight = 90.7712g Weighing of watch glass after hexane evaporation = 90.8850g Mass of crude fats = 0.1138g Percent of crude fats in tissue sample = 45.67%   1.) For adults, the recommended daily intake of fats is around 60g. Based on the class results above, how many grams of the tissue analyzed would you have to consume to meet the daily requirement? 2.) How many insects would have to be consumed to meet the daily requirement? 3.) Butter is about 85% fat, and a typical person spreads about 3g of butter on a piece of toast. How many bugs would you have to spread on your toast for an equivalent amount of fat? 4.) The crude fat could also be converted to methylated fatty acids and used as a biofuel in diesel engines and aircraft. Note the mass of the biofuel is essentially the same as that of the crude fats used to make it. a) If the biofuel has a density of 880g/L, how many grams of insects would be needed to make a…
