A researcher claims that less than 11% of college students are vegetarian. If the alternative hypothesis is $$H_1: p \neq 0.11$$, which of the following is the rejection region for a 10 percent level test ($$\alpha = 0.10$$)? $$Z < -1.645$$ or $$Z > 1.645$$ $$Z < -1.28$$ or $$Z > 1.28$$ $$Z > 1.96$$ $$Z < -1.645$$

Step 1
The problem asks for the rejection region for a hypothesis test given the alternative hypothesis and the significance level. The alternative hypothesis is $$H_1: p \neq 0.11$$. This indicates a two-tailed test. The significance level is $$\alpha = 0.10$$. Show more…

An education researcher claims that 55% of college students work year-round. In a random sample of 600 college students, 330 say they work year-round. At α = 0.01, is there enough evidence to reject the researcher's claim? Complete parts (a) through (e) below: Z0 = 2.57 (Round to two decimal places as needed. Use a comma to separate answers as needed) Identify the rejection region(s). Select the correct choice below and fill in the answer box(es) to complete your choice. (Round to two decimal places as needed) A. The rejection region is Z < -2.57 B. The rejection region is Z > 2.57 C. The rejection regions are -2.57 < Z < 2.57 (C) Find the standardized test statistic Z. Z = (Round to two decimal places as needed) Decide whether to reject or fail to reject the null hypothesis and interpret the decision in the context of the original claim. Null hypothesis: There is enough evidence to reject the researcher's claim.

Question 8 When performing a two-sided 1-proportion z-test, what values for the test statistic, z, are required to reject a null hypothesis at the 10% level? z > 1.960 or z < -1.960 z > 3.100 or z < -3.100 z > 1.645 or z < -1.645 None of these z > 1.290 or z < -1.290

A student at a two-year college would like to test that the mean enrollment at two-year colleges (μ1) is actually lower than the mean enrollment at one-year colleges (μ2) in the United States. Two surveys are conducted. Of the 50 two-year colleges surveyed, the mean enrollment was 1,940 with a standard deviation of 402. Of the 36 one-year colleges surveyed, the mean enrollment was 2,245 with a standard deviation of 378. A hypothesis test is conducted at α = 0.02. State the rejection region. Confidence Level C: 90%, 95%, 96%, 98%, 99%, 99.8% z*: 1.645, 1.960, 2.054, 2.326, 2.576, 3.090 1-Sided P: 0.05, 0.025, 0.02, 0.01, 0.005, 0.001 2-Sided P: 0.1, 0.05, 0.04, 0.02, 0.01, 0.002 z_c < -2.054 or z_c > 2.054 z_c > 2.054 z_c < -2.054 z_c > 2.326 z_c < -2.326 z_c < -2.326 or z_c > 2.326
