USA Today (Feb. 17, 2011) described a survey of 1,008 American adults. One question on the survey asked people if they had ever sent a love letter using e-mail. Suppose that this survey used a random sample of adults and 205 stated that they had written a love letter using e-mail. Is this evidence that more than 20% of American adults have written a love letter using e-mail? Use a level of significance of 5%. a) p: (3 decimal places) b) Complete the following areas. Label the critical value and test statistic on the curve and shade the rejection region(s). Họ: Hi: Type of Test: Test Statistic: (2 decimal places) Critical Value(s): (2 decimal places) P-Value: (4 decimal places) Reject or Fail to Reject:
Four scenarios of statistical studies are given below. Decide which study uses a population parameter. Answer O Lakeside Family Dentistry reported that 6 of the 15 patients who came in for a regular cleaning one day had at least one cavity. O As part of her senior project, Kaisa asked 84 of her classmates if they voted in the last presidential election. 39 said yes. O of 351 dog owners who were surveyed, 70 reported owning two dogs. The average finish time for the Ironman, Kona was 11:32 for the 1883 finishers, with an average swim time of 1:14, an average bike time time of 4:14.
Researchers designed a survey to compare the proportions of children who come to school without eating breakfast in two low-income elementary schools. A random sample of 80 students from School 1 found that 19 had not eaten breakfast. At School 2, a random sample of 150 students included 26 who had not had breakfast. Is there evidence at the 0.05 significance level of a difference in the population proportions? What is the test statistic for this test? A) 1.168 B) 0.2427 C) 0.2375 D) 1.733 E) 0.1957
You wish to test the following claim (Ha) at a significance level of a = 0.01. H.: u = 78.5 H.:u < 78.5 You believe the population is normally distributed, but you do not know the standard deviation.

Teacher Salaries. Data on salaries in the public school system are published annually in Ranking of the States and Estimates of School Statistics by the National Education Association. The mean annual salary of (public) classroom teachers is $55.4 thousand. A hypothesis test is to be performed to decide whether the mean annual salary of classroom teachers in Ohio is greater than the national mean. a. determine the null hypothesis. b. determine the alternative hypothesis. c. classify the hypothesis test as two tailed, left tailed, or right tailed.
In studying the responses to questions on a multiple-choice test, the following sample data are obtained. At the a 0.05 significance level, test the claim that the responses occur with the same frequency. Ho: The responses to the questions occur with the same frequency. H₁: The responses to the questions do not occur with the same frequency. Observed Response Frequency Expected Frequency (0-E)2 E A 6 16.2 8 B 10 16.2 C 24 16.2 D 18 16.2 8 E 23 16.2 a. What is the X2 test-statistic for this data? Round to four decimal places. x²= b. What is the p-value? Round to four decimal places. p-value= c. What would be the conclusion of this hypothesis test? O Fail to reject the hull hypothesis. Reject the null hypothesis. d. What is the final conclusion? O There is sufficient evidence to conclude the test question responses occur with the same frequency. There is sufficient evidence to conclude the test question responses do not occur with the same frequency. O There is not sufficient evidence to…
