An official of a large national union claims that the representation of women in the union is at least 40% (hypothesized population proportion). A researcher believes that the union doesn't have a 40% women representation and conducts the following hypothesis test: Ho: The union has at least 40% women representation Ha: The women representation in the union is less than 40% Using p-value approach and sample information given below, carry out the above hypothesis test. Let the level of significancea for the test in the blank. 0.05. Fill in the required values Sample size (n) Women Men 400 144 256 What is the value of sample proportion? The value of test statistics is (round to two decimal place)

Use the technology display, which results from the head injury measurements from car crash dummies listed below. The measurements are in hic (head injury criterion) units, and they are from the same cars used for the table below. Use a 0.01 significance level to test the given claim. Test the null hypothesis that head injury measurements are not affected by an interaction between the type of car (foreign, domestic) and size of the car (small, medium, large). What do you conclude? Click the icon to view the data table and technology display. What are the null and alternative hypotheses? O A. Ho: Head injury measurements are affected by an interaction between type of car and size of the car.

High-powered experimental engines are being developed by the Hendrix Motor Company for use in their new sports coupe. The engineers have calculated the maximum horsepower for the engines to be 650HP. Sixteen engines are randomly selected for testing. Perform a hypothesis test to determine whether the data suggests that the average maximum horsepower for the experimental engine is significantly different than the maximum horsepower calculated by the engineers. Assume the data are normally distributed and use a significance level of 0.01. Maximum Horsepower (HP) 634 607 688 630 695 635 657 655 678 671 676 689 672 687 680 677 Copy Data Step 2 of 3 : Compute the value of the test statistic. Round your answer to three decimal places.

Suppose we are interested in the relationship between individuals’ place of residence (rural versus urban) and their political affiliation (Republican versus Democrat). A random sample of 100 individuals yields the following crosstabulation: Political Affiliation Place of Residence Republican Democrat Rural 21 29 Urban 14 36 a) In words, what is the null hypothesis to be tested? b) Is the relationship between place of residence and political affiliation statistically significant at the .05 level? (Be sure to show the statistics that lead to your decision.) c) Compute and interpret an appropriate measure of association for the relationship between these two variables.
A scientist selected a random sample of seven varieties of peach ice cream to investigate the relationship between the density, in pounds per cubic inch, of the varieties of ice cream and the percent concentration of peaches in the ice cream.
