Weight loss programs are abundant in the U.S.A.Some cost a membership fee, some do not. But all seem to work (at least temporarily) if the individual "complies" with the program for at least 60 days. Presume that the mean weight loss after 60 days for the population of adults complying to a program, any program, is = 15 pounds, with a standard deviation of= 4.0.You have developed a novel program combining "clean-eating" plus daily aerobic exercise and predict that persons in your program will lose more weight than the national average of 15 pounds in 60 days.Eighteen adults participate in your program and at the end of 60 days have a mean weight loss ofM = 15.83 pounds.Set your alpha level at = .05.Complete steps 3 and 4 of the hypothesis testing procedure. Then summarize the results of the hypothesis testing procedure by putting your results in journal form.Ignore the minus sign if your calculated z or t is negative.[Note, if your calculated z or t is not identical to one of the values below, but within plus or minus 0.2 of an answer below, assume it's a rounding error and select the answer that is closest to your calculated value.]

Group of answer choices

t (17) = 4.05, p < .05

z = .88, p .05

t (17) = .66, p < .05

t (18) = .66, p < .05

z = .88, p > .05

z = 3.77 p < .05
