a. State the hypotheses and identify the claim.
b. Find the critical value.
c. Compute the test value.
d. Make the decision.

Use the traditional method of hypothesis testing unless otherwise specified. Assume all assumptions are valid.
8. Ethnicity and Movie Admissions Are movie admissions related to ethnicity? A 2014 study indicated the following numbers of admissions (in thousands) for two different years. At the 0.05 level of significance, can it be concluded that movie attendance by year was dependent upon ethnicity?

- Given the situation below, create a problem and determine (a) the null and alternative hypotheses, (b) test statistic, (c) rejection region, and (d) applicability of the CLT.arrow_forwardWrite the following five steps of hypothesis test: 1. Set a set of hypotheses 2. Determine rejection rule with a given a (Fa). 3. Compute test statistic (F-Value) 4. Make judgment 5. Interpretation with p-value Utilize excel output to conduct your answers.arrow_forwardUse the five steps in the hypothesis testing procedure for each answer. 1 ) A national publishing house claims that 45% of all weekly magazine readers in South Africa read their publication. Test this claim at the 5% significance level, if a survey found that 205 out of a random sample of 500 magazine readers said that they read the relevant publication.arrow_forward
- You are given the following hypotheses H 0 :p=0.3 H A :p not equal 0.3 We know that the sample size 90. For what sample proportion would the pvalue be equal to 0.1? Assume that all conditions necessary for Inference are satisfied.arrow_forwardYou are given the following hypotheses: H0: p = 0.3HA: p ≠ 0.3 We know that the sample size is 90. For what sample proportion would the p-value be equal to 0.1? Assume that all conditions necessary for inference are satisfied.arrow_forwardA dental assistant is interested in the proportion of patients that need a root canal. Let the proportion of patients that need a root canal be p. If the dental assistant wanted to know if the proportion of patients that need a root canal is more than 20%, what are the null and alternative hypotheses? Select the correct answer below: H0: p=0.20; Ha: p<0.20 H0: p>0.20; Ha: p=0.20 H0: p=0.20; Ha: p>0.20 H0: μ=0.20; Ha: μ>0.20arrow_forward

State the null and alternative hypotheses. b. State which hypothesis test should be used. Calculate the p-Value and state the command you entered in the calculator. c. State the conclusion in the context of the problem.arrow_forwardname the appropriate inference procedure, and write the hypotheses.

Two different methods (A and B) of determining the level of contamination were used on each of eight randomly selected specimens of a certain type of beef. The data obtained, in millimicrobes/liter of ground beef, for each of the methods are shown in the table below. Bacteria 2 Investigators at the U.S. Department of Agriculture wished to compare methods of determining the level of bacterial contamination in beef. Two different methods (A and B) of determining the level of contamination were tested. Sixteen randomly selected specimens of a certain type…arrow_forwardIn performing a hypothesis T-test, the p-value was 0.00046 and the significance level was 5%. What is the conclusion? Is it a,b,or c? a. Reject the null hypothesis and accept the alternate hypothesis b. Accept both the null hypothesis and alternate hypothesis c. Fail to reject the null hypothesisarrow_forward
- A sports enthusiast would like to determine if the average number of penalty minutes per game for teams in the National Hockey League is greater than 12 minutes. A sample of 30 games was taken, and the number of penalty minutes in each game was recorded. Select the appropriate hypotheses to be tested.

H0: σ2=100 HA: σ2≠100 a. Test when n=25, s=9, and α=0.10. Be certain to state the decision rule. State the decision rule. Select the correct choice below and, if necessary, fill in any answer boxes to complete your choice. (Round to four decimal places as needed.) A. If the test statistic, χ2>χ2α=_____, reject H0. B. If the test statistic, χ2<χ21−α=_____, reject H0. C. If the test statistic, χ2>χ20.05= ______, reject H0. or if the test statistic, χ2<χ20.95=______, reject H0.arrow_forwardBrown wants to conduct an assessment of where employees live and how employees work. Brown wanted to know if where you lived was related to how you worked. What hypothesis tests can be used in this case?arrow_forward
