Researchers have been studying the effect of diet on a certain species of rabbit. After making a change in diet, the researchers record the weight gained by a random sample of rabbits. The data is displayed below.

Weight gained (grams): 66, 54.7, 61.8, 61.7, 64.9, 60.3, 64.8, 59.1, 67.5

Checksum: 560.8

Resample the sample (bootstrap) with 1000 iterations to create a 90% confidence interval for the population mean weight gain.

Result: With the new diet, the researchers can be 90% confident that the mean weight gain for all rabbits of this species is between [ ] and [ ] grams.

Researchers studying the effect of diet on growth would like to know if a vegetarian diet affects the height of a child. Twelve students are randomly selected that are all 6-years old. The average height of these kids is 42.5 inches with a standard deviation of 3.8 inches. The average height of all 6-year old kids is found to be 45.75 inches. Conduct a hypothesis test to determine if there is overwhelming evidence at alpha = .05 that 6-year old...

Suppose we are studying the effect of diet on height of children, and we have two diets to compare: diet A (a well-balanced diet with lots of broccoli) and diet B (a diet rich in potato chips and candy bars). We wish to find the diet that helps children grow faster. We have decided to use 20 children in the experiment, and we are contemplating the following methods for matching children with diets: i. Let them choose. ii. Take the...

1. A researcher studying the lifespan of a certain species of bacteria. A preliminary sample of 35 bacteria reveals a sample mean of ¯ x = 64 x ¯ = 64 hours with a standard deviation of s = 5.6 s = 5.6 hours. He would like to estimate the mean lifespan for this species of bacteria to within a margin of error of 0.5 hours at a 98% level of confidence. What sample size should you gather to achieve...

Researchers have been studying the association between cigarette smoking and caffeine intake and Parkinson's Disease for more than 40 years. The results of a study by Checkoway et al. (2002) follow: Ever having smoked cigarettes resulted with an odds ratio (OR) = 0.5 (95% confidence interval (CI): 0.4, 0.8). The OR for current smokers was OR = 0.3 (95% CI: 0.1, 0.7). Among ex-smokers the OR = 0.6 (95% CI: 0.4, 0.9). Interpret the three ORs (in your own words).

Researchers at some of the nation’s leading universities have been studying financial literacy for years. Results from their work provide interesting insights into the financial capabilities of the average American. Their findings are a bit sad. The average American is, well, basically a “C” student when it comes to financial issues— and we are talking about adults! What follows are a number of questions that these researchers asked survey participants to think about. See if you can beat the national...

Researchers are interested in the effect of a certain nutrient on the growth rate of plant seedlings. Using a hyproponics growth procedure that used water containing the nutrient, they planted six tomato plants and recorded the heights of each plant 14 days after gemination. Those heights, measured in millimeters, were as follows : 55.5, 60.3, 60.6, 62.1, 65.5, 69.2. Test the claim that the mean tomato plants’heights is different than 65 millimeters. Assume the random sample assumption holds. Use α...
