Determine if voters’ opinions are independent or dependent of gender.  Set up hypotheses; perform a test for independence; analyze all relevant aspects of your conclusion.

use a hypothesis test to determine if the proportions are statistically different. A recent survey showed that in a sample of 100 elementary school teachers, 15 were single. In a sample of 180high school teachers, 36 were single. Is the proportion of high school teachers who were single greater than theproportion of elementary teachers who were single? Use ΅ = 0.01.

Suppose the P-value in a two-tailed test is 0.0134. Based on the same population, sample and null hypothesis, and assuming the test statistic z is negative, what is the P-value for a corresponding left-tailed test? Select one: O a. 0.0067 O b. 0.0268 O c. 0.225 O d. 0.0184 Next pag

The distribution of majors at the college is shown below. Major Math/Science Arts and Humanities Business and Economics Others Percents 24 33 34 9 Suppose a random sample of 400 athletes from the college are surveyed. The table below shows the results of the survey. Major Math/Science Arts and Humanities Business and Economics Others Frequency 95 146 118 41 What can be concluded at the 0.05 level of significance? Perform the hypothesis test. H0:  The distribution of majors for athletes at the college is the same as the distribution of majors for the general population. H1: The distribution of majors for athletes at the college is not the same as the distribution of majors for the general population. p-Value = [ Select ]  ["0.04", "0.38", "0.21", "0.00"]            Conclusion: [ Select ] ["There is insufficient evidence to support the claim that athletes' majors follow the same or a different distribution as majors from the entire student body.", "There is statistically…

Conduct the hypothesis test and provide the test statistic and the critical value, and state the conclusion. K A person randomly selected 100 checks and recorded the cents portions of those checks. The table below lists those cents portions categorized according to the indicated values. Use a 0.05 significance level to test the claim that the four categories are equally likely. The person expected that many checks for whole dollar amounts would result in a disproportionately high frequency for the first category, but do the results support that expectation? D 0-24 30 Cents portion of check 25-49 24 Number Click here to view the chi-square distribution table. The test statistic is (Round to three decimal paces as needed.) 50-74 19 75-99 27

Suppose are running a study/poll about the accuracy rate for fingerprint identification. You randomly sample 127 people and find that 89 of them match the condition you are testing. Suppose you are have the following null and alternative hypotheses for a test you are running: Ho: p = 0.72 H₁: p 0.72 Calculate the test statistic, rounded to 3 decimal places Question Help: Video Message instructor Post to forum Submit Question

If the level of significance in a hypothesis test is 1 %, what would the p-value have to be for failing to reject the null hypothesis? a. equal to 0.005 b. less than .01 c. greater than .01
