TIMED PLEASE HURRY :) A therapist is studying the effects of meditation and yoga on reducing stress. He offers the treatments to a random sample of 30 of his patients and lets them choose which treatment they want to use.

Which of the following statements is not true about this experiment?

A The therapist let the patients choose the treatment; therefore, he will not be able to tell which treatment is more effective.
B The therapist used a random sample of 30 of his patients; therefore, he will be able to tell which treatment is more effective, yoga or meditation, in reducing stress.
C The therapist did not use random assignment; therefore, the variability between the patients is not evened out, and he will not be able to tell which treatment is more effective.
D The therapist used a random sample; however, the patients may choose which treatment they prefer, and their stress would be reduced due to their preference instead of the treatment.

F(n + 1) = f(n) – 8. if f(1) = 100, what is f(6)?

Solve the problem. a student earned grades of c, a, b, and a in four different courses. those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5. the grading system assigns quality points to letter grades as follows: a = 4, b = 3, c = 2, d = 1, and f = 0. compute the grade point average (gpa) and round the result to two decimal places. 3.40 3.50 8.75 2.18

It appears that people who are mildly obese are less active than leaner people. one study looked at the average number of minutes per day that people spend standing or walking. among mildly obese people, the mean number of minutes of daily activity (standing or walking) is approximately normally distributed with mean 376 minutes and standard deviation 64 minutes. the mean number of minutes of daily activity for lean people is approximately normally distributed with mean 528 minutes and standard deviation 107 minutes. a researcher records the minutes of activity for an srs of 7 mildly obese people and an srs of 7 lean people. use z-scores rounded to two decimal places to answer the following: what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 mildly obese people exceeds 420 minutes? what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 lean people exceeds 420 minutes?
