A Community Center was interested in the effect of their program on summer loss. Summer loss is the decrease in academic knowledge from the summer to the Fall of the new year. To test their program, they drew a random sample of 20 students from the program. The students were assessed before and after the 6 week program on a 36 item assessment. Difference scores were calculated for the 20 students and are summarized below. (These scores were calculated by subtracting the pretest from the post test score.) Difference Scores on Assessment Pre-Post Program (N=20) 2 -6 0 0 6 2 6 6 3 6 6 3 3 3 3 0 2 1 3 1
At .01 significance level, do the results support the effectiveness of the program slowing summer loss?
Create a 90 % confidence interval. How does the confidence interval support your decision?

You are tasked to provide a Fat Gram Calculator program for a
local Weight Loss Center. The program should ask the user for the
name of a food item, the number of calories and the number of fat
grams in the item. The program should display the percentage of
calories that come from fat. If the calories from fat are less than
30 percent of the total calories of the food, it should display a
message indicating that the food...

Suppose a fitness center has two weight-loss programs. Fifteen
students complete Program A, and fifteen students complete Program
B. Afterward, the mean and standard deviation of weight loss for
each sample are computed (summarized below). What is the difference
between the mean weight losses, among all students in the
population? Answer with 95% confidence.
Prog A - Mean 10.5 St dev 5.6
Prog B - Mean 13.1 St dev 5.2

A local community health center identifies childhood obesity as
a problem in the community. They collect data demonstrating that
the problem begins as early as elementary school. They develop a
plan that includes clinical interventions at the health center and
also at the elementary school. They ask the health department to
help them organize an educational campaign and assist in evaluating
the results. Working together, they are able to reduce the obesity
rate among elementary school children by 50%. This...

A weight loss program claims that program participants have a
mean weight loss of at least 10 pounds after 1 month. You work for
a medical association and are asked to test this claim. A random
sample of 30 program participants and their weight losses (in
pounds) after 1 month is listed in the table below. Assume the
population standard deviation is 3. At α = 0.01, is there enough
evidence to reject the program's claim?
Samples: 4.7, 6.0, 7.2,...
