- A veterinarian is interested in researching the proportion of men and women cat owners and believes that the proportion of men cat owners is significantly different than the proportion of women cat owners. The veterinarian decides to obtain two independent samples of men and women cat owners and finds from one sample of 80 men, 30% owned cats. In the second sample of 60 women, 55% owned cats.

Is there convincing statistical evidence at the 0.05 level of significance that the true proportion of individuals who use the competitor’s card is actually greater than 0.65 ?Morgan City Fire Chief Sidney Pyro is concerned about the low efficiency scores that his firefighters receive at the state testing institute. Chief Pyro believes that these scores result because some firefighters are not in good physical condition. Pyro orders 75 randomly selected firefighters to participate in an hour of exercise per day. Another 200 firefighters have no required exercise. After 60 days, all firefighters are tested again by the state. Chief Pyro collects the data and performs a two-sample independent t-test by using SPSS to examine if there is a statistically significant difference between the treatment and control groups; the SPSS results are shown in the table below.

What would you set your alpha-level at? Sarah wants to know how gender impacts heart rate recovery after a maximal exercise test. In order to test this, she has both male and female athletes come into her lab and she measures both resting heart rate before the exercise test and heart rate immediately, 10 minutes, 20 minutes and 30 minutes following the exercise test. In order for her to determine whether heart rate differs pre-post exercise between males and females what statistical test might she use? Why?An automobile mileage study tested the following hypotheses. Hypothesis Conclusion H0: µ 25 mpg Manufacturer’s claim supported Ha: µ 25 mpg Manufacturer’s claim rejected; average mileage per gallon less than stated For σ 3 and a .02 level of significance, what sample size would be recommended if the researcher wants an 80% chance of detecting that µ is less than 25 miles per gallon when it is actually 24?
