A random sample of 10 secretaries was asked to type a certain memorandum using both computers and typewriters, and the time required to finish the task was recorded for each secretary. A test of hypothesis will be conducted to determine if there is enough evidence to conclude that the average time required to type a certain memorandum is faster if female secretaries are using computers rather than typewriters using a 5% level of significance. What is the appropriate null hypothesis? a)The average time required to type a certain memorandum is less than or equal to if female secretaries are using computers rather than typewriters. b)The average time required to type a certain memorandum is lesser if female secretaries are using computers rather than typewriters. c)The average time required to type a certain memorandum is greater if female secretaries are using computers rather than typewriters. d)The average time required to type a certain memorandum is different if female secretaries are using computers rather than typewriters

According to a Pew Research Center study, in May 2011, 33% of all American adults had a smart phone (one which the user can use to read email and surf the Internet). A communications professor at a university believes this percentage is lower among community college students. She selects 352 community college students at random and finds that 122 of them have a smart phone. In testing the hypotheses: Ho: p= 0.33 versus Ha: p < 0.33 Do the hypothesis test. Use a level of significance of a = 0.05; Use the unrounded values in Excel to find the answers for #3 and #4. 1. This is an example of a hypothesis test. 2. Find the standard error. 3.

A random sample of 100 rich men faculty and 100 rich women faculty at a Premier University is asked if they have an automobile on campus. If 31 of the rich men and 24 of the rich women have cars, can we conclude that more men than women have cars on the campus? Use a 0.01 level of significance.

A student wants to see if the number of times a book has been checked out of the library in the past year and the number of pages in the book are related. She guesses that the number of times a book has been checked out of the library in the past year will be a predictor of the number of pages it has.

Christine, a researcher in psychology and biobehavioral health, believes that city residents and residents of rural areas differ in how appealing they find owning a cat. A random sample of 109 people who live in San Antonio were surveyed and 59 identified themselves as a "cat person." A random sample of 108 people who live in the surrounding rural area were selected and 72 identified themselves as a "cat person." Conduct an appropriate hypothesis test at the a = 0.1 significance level to test Christine's claim. Round answers to 4 decimal places where appropriate. a. State the null and alternative hypotheses. Ho: p. H₁: p. b. What is the appropriate distribution to use for the hypothesis test? Z (Normal) c. Find the test statistic. Test Statistic: -1.9593 X d. Determine the P-value: op.

Since an instant replay system for tennis was introduced at a major tournament, men challenged 1434 referee calls, with the result that 417 of the calls were overturned. Women challenged 743 referee calls, and 217 of the calls were overturned. Use a 0.01 significance level to test the claim that men and women have equal success in challenging calls.

To test the fairness of law enforcement in its area, a local citizens’ group wants to know whether women and men are unequally likely to get speeding tickets. Three hundred randomly selected adults were phoned and asked whether or not they had been cited for speeding in the last year. Using the results in the following table and a 0.02 level of significance, test the claim of the citizens’ group. Let men be Population 1 and let women be Population 2. Ticketed Not Ticketed Men 14 165 Women 22 99 Step 1 of 3: State the null and alternative hypotheses for the test Step 2 of 3: Compute the value of the test statistic. Round your answer to two decimal places. Step 3 of 3: Draw a conclusion and interpret the decision.
Xu and Garcia (2008)conducted a research study demonstrating that 8-month-old infants appear to recognize which samples are likely to be obtained from a population and which are not. In the study, the infants watched as a sample of n = 5 ping-pong balls was selected from a large box. In one condition, the sample consisted of 1 red ball and 4 white balls. After the sample was selected, the front panel of the box was removed to reveal the contents. In the expected condition, the box contained primarily white balls like the sample, and the infants looked at it for an average of M = 7.5 seconds. In the unexpected condition, the box had primarily red balls, unlike the sample, and the infants looked at it for M = 9.9. The researchers interpreted the results as demonstrating that the infants found the unexpected result surprising and, therefore, more interesting than the expected result. Assuming that the standard error for both means is σM = 1 second, draw a bar graph showing the two sample…
