A research study showed that waitresses received significantly larger tips when they were wearing red T-shirts compared to other colors. The actual study used a repeated-measures design in which waitresses in five different restaurants wore the same T-shirt in six different colors (red, blue, green, yellow, black, and white) on different days during a six-week period. Each waitress recorded the average tip received while wearing red and the average while wearing another color and computed the difference between the two scores. A similar study also found that were higher when waitresses wore red, with a mean difference of MDD = 32 cents for each $10 of restaurant bill for a sample of n = 11 waitresses. If the difference scores had s² = 539, are the data sufficient to decide that tips are significantly higher when waitresses wear red? Test with a = .01.

In this assignment students will demonstrate their understanding of the distribution of means doing all steps of hypothesis testing. For each problem students will write out all steps of hypothesis testing: 1. State the null and research hypotheses. 2. Set the level of risk associated with the null hypothesis. 3. Select the appropriate test statistic. 4. Compute the test statistic value (called the obtained value). 5. Determine the value needed for rejection of the null hypothesis using the appropriate table of critical values for the particular statistic. 6. Compare the obtained value and the critical value. 7. Make your decision. After completing of the steps of hypothesis tests, write out your results in APA format and in easy-to-understand language 3. A psychologist has developed a standardized test for measuring the vocabulary skills of 4-year-old children. The scores on the test form a normal distribution with μ = 72 and σ = 12. A researcher would like to use this test to…

Movie Theater Attendance: The data shown are the movie admissions, in thousands, of people attending movie theaters over two different time periods. At α = 0.05, is there a difference in the means for the movie attendance for these time periods? Use the traditional method of hypothesis testing unless otherwise specified. State the hypotheses and identify the claim. Find the critical value. Compute the test value. Make the decision. Summarize the results.

Describe the type I error. Choose the correct answer below. OA. A type I error will occur when the actual proportion of new customers who return to buy their next piece of furniture is at least 0.40, but you fail to reject Ho: p20.40. OB. A type I error will occur when the actual proportion of new customers who return to buy their next piece furniture is at least 0.40, but you reject Ho: p20.40. OC. A type I error will occur when the actual proportion of new customers who return to buy their next piece of furniture is no more than 0.40, but you reject Ho: p ≤ 0.40. OD. A type I error will occur when the actual proportion of new customers who return to buy their next piece f furniture is no more than 0.40, but you fail to reject Ho: p ≤0.40.

Identify the claim and state Ho and H Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed, and whether to use a z-test, a t-test, or a chi-square test. Explain your reasoning. Find the critical value(s), identify the rejection region(s), and find the appropriate standardized test statistic. Decide whether to reject or fail to reject the null hypothesis. Interpret the decision in the context of the original claim. A government agency reports that the mean amount of earnings for full-time workers ages 25 to 34 with a master’s degree is less than $70,000. In a random sample of 15 full-time workers ages 25 to 34 with a master’s degree, the mean amount of earnings is $66,231 and the standard deviation is $5945. At α = 0.05, is there enough evidence to support the agency’s claim? Assume the population is normally distributed.
