An animal’s maintenance caloric intake is defined as the number of calories per day required to maintain its weight at a constant value. We wish to discover whether the median maintenance caloric intake, m, for a population of rats is less than 10g/day. We draw a SRS of 17 rats, feed each rat 10g of dry food per day for30 days, and find that 4 of the rats lost weight, while the rest gained weight.

(a) State null and alternative hypotheses in terms of m.

(b) Let B be the number of rats in a SRS of size 17 that exhibit daily caloric demands more than 10g/day.IfH0is true, what is the distribution ofB?

(c) What is the value of B observed in the study?

(d) Use the sign test to calculate the p-value and draw a conclusion using α= 0.05.

Suppose that the mean caloric intake for Americans is 2,500 calories per day, with a standard devia- tion of 175 calories per day. Assume that caloric intakes for Americans are approximately normally distributed. (a) (3 points) Find the probability that a randomly selected American consumes more than 2,250 calories per day. (b) (3 points) Find the probability that a randomly selected American consumes at most 1,950 calo- ries per day. (c) (3 points) Find the probability that a randomly selected...

Day 1 Caloric intake: 859 kcals Day 2 Caloric Intake: 1207 kcals Day 3 Caloric Intake: 437 kcals It has been postulated that an excess of 3,500 calories = 1 pound of fat gain. Likewise, a deficit of 3,500 calories results in 1 pound of fat loss. For the purpose of this question, we will assume that all excess calories you eat are stored as fat. Based on your answer to the question above, if your current calorie intake pattern...

6. The American Dietetic Association recommends a dietary intake of 2,000 calories per day. A sample of 438 college athletes in a study of obesity report a mean intake of 2,812 calories per day, with a standard deviation of 206 calories. Based on the sample data, is the caloric intake of college athletes greater than the American Dietetic Association’s recommendations? Run the appropriate test at a 5% level of significance.

For a diabetic, the number of meals and quantity of calories in a day are very important to monitor. A diabetic monitored the number of times he eats in a day but since he leads a busy schedule he cannot always eat appropriately. Let X represent a discrete random variable of the number of meals that this diabetic consumes in a day. The following represents the probability distribution of X: X 1 2 3 4 5 P=(X=x) 0.10 0.12 0.50...
