- In an experimental study of the longevity of Drosophila melanogaster (fruit fly) 70 male adults and 75 female adults were observed until the death of the last member in each group. The mean lifetime for the males was found to be 43.2 days with a standard deviation of 9.1 days. The corresponding figures for the females were 37.5 days and 8.8 days. Would you conclude that the male Drosophila has a greater longevity than the female?

In a sample of 100 obese people on a low-fat diet the sample mean weight loss as 7.6 pounds with a standard deviation of 3.2 pounds. In another sample of 120 obese people on a low-carb diet the sample mean weight loss was 6.7 pounds with a standard deviation of 3.9 pounds. a) Test the hypothesis, at the 5% level of significance, that there is a difference in the mean weight loss of using the 2 different diets. b) What is the p-value?arrow_forwardAn educational consulting group claims that there is a difference in the mean student loan debt of students who attended private four-year colleges and the mean student loan debt of students who attended out-of-state public four-year colleges. Student loan debt of 10 randomly selected students who attended private four-year colleges and 10 randomly selected students who attended out-of-state public four-year colleges, at the time of graduating college, are recorded. Assume that the population standard deviation of student loan debt is $5,000 for both the private college attendees and the public college attendees, and assume that the distribution of student loan debt is normally distributed for both the private college attendees and the public college attendees. Let the students who attended private four-year colleges be the first sample, and let the students who attended out-of-state public four-year colleges be the second sample.

- The measurement of head circumference is closely tracked in pediatric medicine. Microcephaly (defined as a head circumference 2.0 standard deviations below average for weight and gender) or macrocephaly (defined as a head circumference 2.5 standard deviations above average for weight and gender) are markers of possible developmental abnormalities. According to Örmeci, Gürbüz, Ayata, and Çetin (1997), the average cranium for an adult female in Turkey measures 54.57 cm in circumference, with a standard deviation of 1.61 cm. We use the responses students in our class made to the survey at the beginning of the semester to compare the average head size for the women in our class in the United States to the population average taken from the women in Turkey. What statistical test should be used and why?arrow_forwardAccording to a study on reptiles from decades ago, the mean lifespan of giant Aldabra tortoises in the wild is 98.3 years. Many of the areas where these tortoises live have become polluted with plastic waste. Because of this, a biologist claims the mean lifespan of these tortoises has decreased. To test this claim, the biologist conducted a study of 21 randomly selected, giant Aldabra tortoises in the wild. In the study, the sample mean lifespan was 96.3 years with a sample standard deviation of 15.2 years. Assume that the population of lifespans of giant Aldabra tortoises in the wild is approximately normally distributed. Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.10 level of significance, to support the claim that μ , the mean lifespan of giant Aldabra tortoises in the wild, is now less than 98.3 years.

A study of browser- based shopping sessions reported that Pinterest shoppers spent a mean of $ 153 per order and Facebook shoppers spent a mean of $ 85 per order.

Suppose that the study consisted of 500 Pinterest shoppers and 500 Facebook shoppers, and the standard deviation of the order value was $ 150 for Pinterest shoppers and $ 80 for Facebook shoppers. Assume a level of significance of 0.05. Is there evidence of a difference in the variances of the order values between Pinterest shoppers and Facebook shoppers?
