A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 324 people over the age of 55, 72 dream in black and white, and among 296 people under the age of 25, 18 dream in black and white. Use a 0.01 significance level to test the claim that the proportion of people over 55 who dream in black and white is greater than the proportion for those under 25. Complete...

A study observed two samples of people, the first classified as “athletic” and the second as “nonathletic”. Among the 300 classified as “athletic”, it was found that 48 regularly eat a certain breakfast food. Among the 200 “non-athletic” persons, there were 52 who regularly eat this breakfast food. We want to study whether there is a difference in the proportions in consumption of this breakfast food between the “athletic” and the “non-athletic” groups. What is the chi square statistics?

A study of cats and dogs found that 21 of 50 cats and 32 of 55 dogs slept more than 10 hours per day. At the .05 level of significance, does this sample data provide sufficient evidence to conclude that a difference exists between the proportion of cats and the proportion of dogs that sleep more than 10 hours per day? O No, there is not sufficient evidence to reject the hypothesis that the proportions are the samebecause the test...

We want to make a comparison on the proportion of deaths due to
lung cancer in the general population of chemical plant workers
versus the proportion of deaths due to lung cancer for those
working in a new chemical plant. We draw a sample and find the
proportion of deaths due to lung cancer in the general population
of chemical plant workers nationwide is estimated at 12.8% (n=250).
Suppose that of 100 deaths that occurred in a new chemical plant,...
