- On a psychology exam with µ= 76 and o = 12, Tom scored 9 points below the mean (M), Mary %3D had a score of X=70, and Bill had a z-score of z = -1.00. Place these three students in order from lowest to highest score:arrow_forwardUse the following for the next 3 problems. Is there a difference in the amount of airborne bacteria between carpeted and uncarpeted rooms? In an experiment, 7 rooms were carpeted and 7 were left uncarpeted. The rooms are similar in size and function. After a suitable period of time, the concentration of bacteria in the air was measured (in units of bacteria per cubic foot) in all of these rooms. Assume the populations are normally distributed. The following is a summary of the data: Carpeted rooms: Uncarpeted rooms: X 184 175 S 22.0 16.9 19. A 95% confidence interval for the difference in mean bacterial concentration in the air of carpeted rooms versus uncarpeted rooms is (use 11 degrees of freedom). O -7.47 to 31.47. O -18.89 to 42.89.

A study from the year 2000 showed 132 cases of myopia in 400 randomly selected people. A separate study from 2018 showed 228 cases in 600 randomly selected people. Is there enough evidence to support the researcher's suspicion that the proportion of myopia cases in 2018 is higher than the proportion of myopia cases in 2000? Use alpha = 0.05. Let P1 represent the proportion of myopia cases in 2018 and let p2 be the proportion of myopia cases in 2000. 1) State Ho and Ha 2) Calculate the value of the test statistic, z (round to 2 decimal places) 3) Calculate the p-value (round to 4 decimal places) 4) Decide to reject or fail to reject Ho 5) Write your conclusion in the context of the claim.
