Measuring lung function: One of the measurements used to determine the heelth of a person's lungs is the amount of air a person can exhale under force inone second. This is called the forced expiratory volume in one second, and is abbrevlated FEV, Assume the mear FEV for 10-year-cld boys is 2.1 liters andthat the population standard deviation is oto have a sample mean FEV, of 2.05 liters. Can you conclude that the mean FEV. in the high-pollution community is less than 2.1 liters? Use the a=0.10 levelof significance and the P-value method with the table.0.4.

Past research has indicated that the average age of death row inmates is 41 years old. researcher would like to determine if the average age has changed. She randomly selects 50 death row inma s and ds their average age to be 37 years old. The hypothesis the statistician wants to test is: a. Ho: µ=37 vs_ Ha: µ ± 41. b. Ho: µ=41 vs Ha: µ< 41. Ho: u = 41 vs. H: u 41 d. Ho: µ=37 vs_Ha: µ< 41. C. 2. If a player at a casino is playing roulette and betting on red, there is a 18 / 38 or 0.474 chance that he will win on any spin of the roulette wheel.
