Jerry is considering opening a new ice cream store at a certain location on State Street in Madison. Jerry conducts some analysis and determines that a given location is acceptable only if the number of pedestrians passing the potential location averages more than 100 per hour. To check if this location is acceptable, Jerry records the number of pedestrians observed for each of 40 hours. Jerry finds that the average number of pedestrians that pass the potential location during each of the 40 hours he was observing, is 105.7 per hour. Jerry assumes that he knows the population standard deviation to be 16. Can Jerry conclude at the 1% significance level that the potential location for the ice cream store is acceptable? a. What is the correct set of hypotheses? Answer: Ho: u = 100 and H1: u> 100 v b. Determine the p-value Answer: 0.0122 c. Interpret the results Answer: There is not enough evidence d.

In a recent year, a research organization found that 487 of 806 surveyed male Internet users use social networking. By contrast 619 of 919 female Internet users use social networking. Let any difference refer to subtracting male values from female values. Complete parts a through V below. Assume that any necessary assumptions and conditions are satisfied. Find the proportions of male and female Internet users who said they use social networking. A. What is the difference in proportions? B. What is the standard error of the difference? C. Find a 95% confidence interval for the difference between these proportions.
A third-grade teacher is interested in comparing the effectiveness of two styles of instruction in language comprehension: imagery, in which the students are asked to picture a situation involving the word, and repetition, in which the students repeat the definition of the word multiple times. After 6 weeks of instruction, she gives the students a language comprehension test. The following scores are the number of correct answers for each student. Determine whether the two styles of instruction differ in their effectiveness. Imagery: 12, 13, 11, 11, 13, 13, 15, 12, 9, 12 Repetition: 6, 11, 10, 12, 9, 10, 11, 12, 10, 8 Answer the quetions in picture provided using above information. Thank you
Amy has two ways to travel from her home in Norco to her office in Los Angeles. One is to go via the 10 Freeway, and the other is to go via 60 Freeway. In order to determine which way she should travel on a daily basis, Amy has recorded the travel times for samples of eight trips via the 10 Freeway and eight trips via the 60 Freeway. The following table gives the travel times (in minutes) for the sixteen trips: Travel times in minutes 10 Freeway 73, 69, 72, 71, 73, 73, 72, 73 60 Freeway 80, 75, 68, 72, 73, 81, 67, 75 Assume that the two populations of travel times are normally distributed and that the population variances are equal. Can we conclude, at the 0.1 level of significance, that the mean travel times of the two routes are different? Perform a two-tailed test. Then fill in the table below. Carry your intermediate computations to at least three decimal places and round your answers as specified in the table. (If necessary, consult a list…
A researcher wants to determine the specificity of mammograms to determine how effective they are at diagnosing women who have breast cancer. Assume the researcher obtained the results below from a study: Out of a total of 18 women with breast cancer, 12 screened positive and 6 screened negative on the mammogram. Out of a total of 82 women without breast cancer, 5 screened positive and 77 screened negative on the mammogram. Calculate and interpret the specificity of mammograms for detecting breast cancer.
The shortage of organs for transplant is a continuing problem. At the end of 2000, there were 3536 people waiting for a heart transplant, 3355 for a lung transplant, 16,012 for a liver transplant, and 46,824 for a kidney transplant. Corresponding figures for 2003 were 3292, 3543, 16,985, and 56,590, respectively. In 2006, the figures were 2625, 2691, 16,882, and 68,412, respectively.
