The concerns expressed by Barstow reflect which of the following ideas? (A) A primary reason for the European witch-hunts was gender stereotypes. (B) Women were the only victims of the European witch-hunts. (C) Historians should devote more study to the effects of the European witch-hunts. (D) The Reformation raised debates about the female role in society.

In the 2012 GSS, 605 of 790 males and 822 of 977 females indicated a belief in life after death.

Construct a 2 x 2 contingency table relating gender of respondent (SEX, categories male and female) as the rows to belief about life after death (POSTLIFE, categories yes and no) as the columns.

Construct contingency tables using gender, major, plans to go to graduate school, and employment status. (You need to construct six tables, taking two variables at a time.) Analyze the data at the 0.05 level of significance to determine whether any significant relationships exist among these variables.

Use the graphing strategy outlined in this section to graph the rational functions.

$$f(x)=\frac{1-9 x^2}{\left(1-4 x^2\right)^3}$$

In order to test for a gender gap in the way that citizens view the current President, the Tomkins Company polls exactly 500 men and 500 women randomly selected from adults in the United States. Assume that the numbers of adult men and women are the same. Does this sampling plan result in a random sample? A simple random sample? Explain.

In a choice between a VR 25 and a VR 75 schedule of reinforcement, your best strategy would be to choose the _________ schedule (100/50/25)% of the time.

A systolic blood pressure of 120 would be considered normal. One of 150 would be high. But since blood pressure varies with gender and increases with age, a better gauge of the relative standing of your blood pressure would be obtained by comparing it with the population of blood pressures of all persons of your gender and age in the United States. Of course, we can not supply you with that data set, but we can show you a very large sample selected from it. The blood pressure data on 1910 persons, 965 men and 945 women between the ages of 15 and 20, are found at the CourseMate Web site. The data are part of a health survey conducted by the National Institutes of Health (NIH). Entries for each person include that person's age and systolic and diastolic blood pressures at the time the blood pressure was recorded.

How do you blood pressure compare with that of others of your same gender? Check your systolic blood pressure against the appropriate histogram in part 3 or 4 to determine whether your blood pressure is "normal" or whether it is unusually high or low.

What is your working hypothesis at this stage? List the tests you would use to rule out the various causes of midline neck pain.

Before the development of modern landfills, trash was discarded in pits and open dumps. Explain how today’s landfills are an improvement over this waste-disposal strategy.

Write nested if statements that perform the following tests: If amount1 is greater than 10 and amount2 is less than 100, display the greater of the two.

Following table is showing showed the associations between death penalty opinion and gender or race.

To make an inference about the strength of association in the population, you can construct confidence intervals around the sample differences of proportions. The 95% confidence intervals are (0 .1 5, 0.28) comparing whites and blacks and (0 .04 , 0.12) comparing males and females. In the population, can you make a conclusion about which variable is more strongly associated with the death penalty opinion? Explain.

SAT scores for the entering class of 2010 at Oxnard University were normally distributed with a mean of 1340 and a standard deviation of 90. Bob’s SAT score was 1430. (a) Find Bob’s standardized z-score. (b) By the Empirical Rule, is Bob’s SAT score unusual?

(a) Recall: How does Gandhi plead to the charges against him?
(b) Infer: Why do you think he resists the strategy of claiming to be innocent?

Refer to the Materials Performance (Mar. 2013) study to compare two tests for steel corrosion of underground piping. The two tests, which engineers call "instant-off" and "instant-on" potential, were applied to buried piping at a petrochemical plant in Turkey. Recall that both the "instant-off" and "instant-on" tests were used to make predictions of corrosion at each of 19 different randomly selected pipe locations. The researchers want to compare the mean accuracy of the corrosion predictions for the two tests in order to determine if one test is more desirable than the other when applied to buried steel piping. a. What are the experimental units for this study? b. What type of design is employed? Identify the features (e.g., treatments, blocks) of the design. c. What is the dependent (response) variable of interest? d. Illustrate the layout of this design. e. State $H_0$ and $H_a$ in symbols.
