Chapter 1: Problem 76

To examine whether eating brown rice affects metabolism, we ask a random sample of people whether they eat brown rice and we also measure their metabolism rate.

Short Answer

Expert verified
Whether or not eating brown rice affects metabolism rates depends on the results of the statistical analysis. If there is a significant difference in the metabolism rates of those who eat brown rice compared to those who don't, then it can be concluded that brown rice does have an effect on metabolism.

Step by step solution

01

Collect the data

This involves finding a random sample of people and asking them whether they eat brown rice or not. Simultaneously, their metabolism rates are measured.
02

Organize the data

Organize the data into two groups: those who eat brown rice and those who don't. Within each group, the metabolism rates should be arranged in ascending or descending order.
03

Describe the data

Calculate the measures of central tendency (mean, median, mode) and dispersion (variance, standard deviation) for metabolism rate in each group. This gives an idea about the average metabolism rate and how much the rates vary within each group.
04

Visualize the data

Plotting the data can often be useful to visualize the distribution of metabolism rates within each group. Box plots, histograms or dot plots can be used for this purpose.
05

Analyze the data

Determine if there are any clear differences between the two groups鈥� metabolism rates. More formal statistical tests, like t-tests or chi-square tests, may be needed to determine if any observed differences are statistically significant.
06

Interpret the results

Based on the statistical analysis, interpret the relationship between eating brown rice and metabolism rate. If the difference is significant, it can be concluded that eating brown rice does have an effect on metabolism rate.

Spiders regularly engage in spider foreplay that does not culminate in mating. Male spiders mature faster than female spiders and often practice the mating routine on not-yet-mature females. Since male spiders run the risk of getting eaten by female spiders, biologists wondered why spiders engage in this behavior. In one study, \(^{9}\) some spiders were allowed to participate in these nearmatings, while other maturing spiders were isolated. When the spiders were fully mature, the scientists observed real matings. They discovered that if either partner had participated at least once in mock sex, the pair reached the point of real mating significantly faster than inexperienced spiders did. (Mating faster is, apparently, a real advantage in the spider world.) Describe the variables, indicate whether each variable is quantitative or categorical, and indicate the explanatory and response variables.

Strawberry Fields A strawberry farmer has planted 100 rows of plants, each 12 inches apart, and there are about 300 plants in each row. He would like to select a random sample of 30 plants to estimate the average number and weight of berries per plant. (a) Explain how he might choose the specific plants to include in the sample. (b) Carry out your procedure from (a) to identify the first three plants selected for the sample.

For the situation described: (a) What are the cases? (b) What is the variable and is it quantitative or categorical? Collect data from a sample of teenagers with a question that asks "Do you eat at least five servings a day of fruits and vegetables?"

Interviewing the Film Crew on Hollywood Movies There were 136 movies made in Hollywood in 2011. Suppose that, for a documentary about Hollywood film crews, a random sample of five of these movies will be selected for in-depth interviews with the crew members. Assuming the movies are numbered 1 to \(136,\) use a random number generator or table to select a random sample of five movies by number. Indicate which numbers were selected. (If you want to know which movies you selected, check out the dataset HollywoodMovies2011.)

State whether or not the sampling method described produces a random sample from the given population. Send an email to a random sample of students at a university asking them to reply to the question: "Do you think this university should fund an ultimate frisbee team?" A small number of students reply. Use the replies to estimate the proportion of all students at the university who support this use of funds.
