Please answer the 3 part question below. Thank you!
Question 1
Recorded weight losses in lbs for 21 participants of three
different diet programs were:
a) Run Hartley’s F-max test. Does evidence
suggest the variances could be different at
the α = 5% level of significance? Explain, and show any work you
can.
b) The other ANOVA conditions (normality,
independent random samples) were reasonably
satisfied, so I ran an analysis of variance, and here is the
incomplete table of output....

Are all disciplines in the University equally boring or there are some more boring than others? To answer that question, a study performed at Columbia University counted the number of times per 5-minute interval when professors from three different departments said “uh” or “ah” during lectures to fill gaps between words. These counts were used as a proxy (approximation) for the measure of class boredom. The data from observing one hundred of 5-minute intervals from each of three departments’ professors were recorded in...

1. Weight Watchers claims that people following their program can expect to lose more than 10 lbs in 2 months with a standard deviation of 1.3 lbs. Researchers selected a group of 50 people participating in the program and monitored their weight loss over 2 months. The mean weight loss over the 2 months was 10.4 lbs. We want to know if this result supports Weight Watchers’ claim. a. Draw a normal curve for the sampling distribution of samples of...

4. Nutrition scientists can calculate the amount of weight gain that would be associated with a given increase in calories. In one study, 16 non-obese adults, aged 25 to 36 years, were fed 1000 calories per day in excess of the calories needed to maintain a stable body weight. The subjects maintained this diet for 8 weeks, thus consuming a total of 56,000 calories extra. According to theory, 3500 extra calories will translate to weight gain of 1 pound. Therefore,...
