A neuropsychologist wants to determine if people who have a dominant right cerebral hemisphere (right brain dominant) differ from people with a dominant left cerebral hemisphere (left brain dominant) in their choice of either music or reading as a preferred activity. He surveyed 127 subjects with the following results.

Left Brain Dominant Right Brain Dominant

Music 48 18

Reading 35 26

a. Describe (1) the independent variable and its levels, and (2) the dependent variable and its scale of measurement.

b. Describe the null and alternative hypotheses for the study described.

7. A nutritionist wants to determine whether people who regularly drink one protein shake per day have different cholesterol levels than people in general. In the general population, cholesterol is normally distributed with μ = 190 and σ = 30. A person followed the protein shake regimen for two months and his cholesterol is 155. Use the 1% significance level to test the nutritionist’s idea. Use the five steps of hypothesis testing. Explicitly label each of these five steps. Draw...

It is known that roughly 2/3 of all human beings have a dominant right foot or eye. Is there also right-sided dominance in kissing behavior? An article reported that in a random sample of 112 kissing couples, both people in 70 of the couples tended to lean more to the right than to the left. (Use α = 0.05.) (a) If 2/3 of all kissing couples exhibit this right-leaning behavior, what is the probability that the number in a sample...

The business college computing center wants to determine the proportion of business students who have laptop computers. If the proportion exceeds 30%, then the lab will scale back a proposed enlargement of its facilities. Suppose 250 business students were randomly sampled and 75 have laptops.

A public health researcher wants to collect data about race of people who have HIV. His hypothesis is that HIV rates will affect African Americans differently than other races. What would the null hypothesis be for this study? What is the research hypothesis? The researcher publishes an article saying that there were, in fact, more African Americans with HIV than other races with the disease in his study. Did the researcher fail to reject or reject the null hypothesis? A...
