Statistics
Two different models are available for the same machine. The production statistics (number of units produced per hour) of these two models are given below. The data was collected on different days.
Model A
180
176
184
181
190
137
Model B
195
194
190
192
187
185
187
Will you conclude that Model A and Model B have the same productivity?

It is well documented that cholesterol over 200 is a risk factor in developing heart disease for both men and women (www.livestronge.com, January 11, 2011). Younger men are known to have higher cholesterol levels than younger women; however, beyond the age of 55, women are more likely to have higher cholesterol levels. a recent college graduate working at a local blood lab has access to the cholesterol data of 50 men and 50 women in the 20 - 40 age...

A manufacturer of home products is designing a new wall mount for large flat-panel televisions. Since some flat-panel televisions weigh up to 100 pounds, the manufacturer wants to make sure that the mean weight of failure for the wall mounts is greater than 180 pounds. Dayton is a researcher for the manufacturer who is conducting the test. He randomly selects 35 wall mounts and tests them by using a machine that pulls down on the mounts until each one fails....

Maintaining a healthy weight is important for women’s health. Some physicians recommend being back to your pre-pregnancy weight six months after giving birth. Public health officials are interested in whether this is a realistic goal. Do the women in North Carolina weigh more than their pre-pregnancy weight six months postpartum? In other words, is the six months post-pregnancy weight greater than their pre-pregnancy weight? Use a paired samples t-test to compare pst6wght (variable 1) and prewght (variable 2). This uses...

The mean weight of U.S. men of age 30–39 years old is 191.802 pounds. Using the provided sample data file, conduct a one-sample ?-test of a mean to test whether the mean weight of men of age 30–39 years old who smoke daily is lower than 191.802. Calculate the sample mean, x¯, for this data. Give your answer precise to at least one decimal place: Compute the standard deviation, SD, of the sampling distribution of the mean.

Four factors influence the taste of pizza: crust (A),
toppings (B), temperature (C), and sauce
(D). Each can be run at two levels, producing a
24 design. At each run in the design, samples of pizza
are given to a test panel consisting of 20 people. Each tester
assigns a point score from 1 to 10 to the pizza. Total score is the
response variable, and the objective is to find a formulation that
maximizes the total score. Two replicates...
