2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.

The table provides details on the amount of sugar (in grams) and the calorie count in one serving for a sample of 13 varieties of cereal.

| Sugar (grams) | 4 | 13 | 13 | 11 | 7 | 6 | 6 | 2 | 7 | 12 | 20 | 3 | 15 |
|---------------|---|----|----|----|---|---|---|---|---|----|----|---|----|
| Calories | 120 | 200 | 140 | 110 | 120 | 80 | 190 | 100 | 120 | 190 | 190 | 110 | 120 |

a. Make a 95% confidence interval for $ B $.

Round your answers to three decimal places.

\[ [ \ \ ] \quad \text{to} \quad [ \ \ ] \]

b. It is well known that each additional gram of carbohydrate adds 4 calories. Sugar is one type of carbohydrate. Using a regression equation for the data in the table, test at the 1% significance level whether $ B $ is different from 4.

Based on a 1% significance level test, we conclude that $ B $ [ \text{is} / \text{is not} ] different from 4.

A car dealership would like to develop a regression model that would predict the number of cars sold per month by a dealership employee based on theemployee's number of years of sales experience. The accompanying regression output was developed based on a random sample of employees. a. Predict the sales next month for an employee with 2.5 years of experience. The predicted sales is 8.6 cars. b. Compute the coefficient of determination and interpret its meaning. The coefficient of determination is 0.234 Therefore, about _________% of the variation in monthly sales is explained by the years of sales experience.

z Test for Proportions An automobile owner found that 20 years ago, 76% of Americans said that they would prefer to purchase an American automobile. He believes that the number is much less than 76% today. He selected a random sample of 56 Americans and found that 38 said that they would prefer an American automobile. Can it be concluded that the percentage today is less than 76%? At α = 0.01, is he correct?
