1. When conducting a hypothesis test, the hypothesis that illustrates the initial claim being tested about the population is called the ___________________________, whereas the hypothesis that illustrates what we really think is going on is called the ______________________.

A. research hypothesis; null hypothesis B. alternative hypothesis; research hypothesis C. null hypothesis; alternative hypothesis D. alternative hypothesis; null hypothesis E. theoretical hypothesis; realistic hypothesis

2. When conducting a hypothesis test, what would it mean if the researcher obtains a negative test statistic?

A. The sample is too small. B. It's very unlikely the results would have occurred just by chance alone. C. The sample statistic is smaller than the claimed population parameter. D. A mistake was made in terms of calculating the test statistic. E. The sample statistic is larger than the claimed population parameter.

3. A P-value

A. can be positive or negative. B. can only range in value from -1 to 1. C. can be smaller than 0 but no larger than 1. D. can be larger than 1 but no smaller than 0. E. can be no smaller than 0 and no larger than 1.

4. It has recently been claimed that 25% of adults consider spring to be their favorite season of the year. A researcher is skeptical of this claim and believes this percentage is too low. She surveys a random of 1,000 adults and finds that 390 of these adults consider spring to be their favorite season of the year. As she prepares to conduct a hypothesis test, the researcher writes out her alternative hypothesis as "p < 0.25." What is wrong with this?

A. The alternative hypothesis should be "p > 0.39." B. The alternative hypothesis should be "p < 0.39." C. The alternative hypothesis should be "p > 0.25." D. The alternative hypothesis should be "p = 0.25." E. Nothing is wrong with the given alternative hypothesis.

5. A claim is made that the proportion of college students who have Netflix accounts is 0.92. Mateo believes this claimed value is too high. He is able to survey a random sample of 180 college students, and he finds that the sample proportion who have Netflix accounts is 0.88. Mateo proceeds to use this data to conduct a hypothesis test. Based on this information, which one of the following statements is correct?

A. The P-value will be smaller than 0.01 but larger than 0. B. The P-value will be between 0.01 and 0.05. C. The P-value will be between 0.05 and 0.10. D. The P-value will be larger than 0.10. E. The P-value will be negative.

6. Facebook claims that 5.6% of its users are under the age of 18 years. Believing this claimed value is incorrect, a researcher surveys a large random sample of 750 Facebook users and finds that 51 of the Facebook users in the sample are under the age of 18 years. This means the test statistic will equal approximately what value? As you are engaging in calculations, try not to do a lot of rounding until you get to the very end, and choose the answer that is closest to what you calculate.

A. 2.5 B. 1.4 C. 0.8 D. Less than 0.1 E. More information is needed in order to be able to determine the test statistic.

7. In the population of students at Milpitas High School, the proportion who are in the marching band is 0.10. In a random sample of 100 students from this population, the proportion who are in the marching band is 0.04. We would call the value 0.04 a

A. statistic. B. parameter. C. z-score. D. P-value. E. significance level.

8. Which one of the following statements is correct?

A. If you are given a sample percentage of 73%, you would need to know the sample size in order to convert this percentage to a proportion. B. The test statistic is not affected by the size of the sample. C. The larger the P-value, the more evidence you have against the null hypothesis. D. We always begin a hypothesis test by assuming that the null hypothesis is true. E. None of the above statements are correct.

9. It is claimed that 12% of households in the United States generally tune in to watch the Academy Awards. If we were to conduct a hypothesis test based on this claim, the null hypothesis would be Ho: p = 0.12. In this hypothesis, what does p represent?

A. The P-value B. The population proportion C. The sample proportion D. The significance level E. The margin of error

10. Consider a hypothesis testing situation in which the null hypothesis is p = 0.48 and the alternative is p > 0.48. Data is gathered from a random sample, and calculations yield a value of z = 2.5. Which one of the following conclusions can be drawn based on this information?

A. The P-value is larger than 0.10. B. There is a 2.5% chance that the null hypothesis is true. C. The value of 0.48 is called a statistic. D. The sample size must have been large. E. None of the above answers are correct.
