Tucson State University offers two MBA programs. In the first program, the students meet two nights per week at the university's main campus in downtown Tucson. In the second program, students only communicate online with the instructor. The director of the MBA experience at Tucson wishes to compare the number of hours studied last week by the two groups of students. A sample of 10 on- campus students and 12 online students revealed the following information. 28 16 42 29 31 22 50 42 23 25 Campus Online 26 42 65 38 29 32 59 42 27 41 46 18

Dean for student affairs of a small university is worried about students’ expenditure on internet expense during the period study from home since this Covid-19 outbreak. Especially she wants to know whether students of social sciences spend more compared to students from science and technology. As a quick and preliminary study, she collected a sample of 9 students from science and technology and 11 students from social sciences. Total spending for internet is in Rp0000 during the month of April 2029. The results are presented in the following table. Questions: 1. Explain whether you can or cannot use normal approach to the case. 2. Conduct the test by showing formal steps in hypothesis test (design, decision rule, statistical test, and conclusion) at α = 0.05
Four lighting methods were used in each of three rooms. For each method and each room, the illuminance (in lux) was measured in three separate occasions, resulting in three replications of the experiment. The only effect of interest is the lighting type; the room is a blocking factor. The following sums of squares were calculated: sum of squares for blocks = 11432, sum of squares for treatments = 9943, sum of squares for interactions = 6135, total sum of squares = 51376. a) Construct an ANOVA table. You may give ranges for the P-values. b) Are the assumptions for a randomized complete block design satisfied? Explain. c) Does the ANOVA table provide evidence that lighting type affects illuminance? Explain.
Based on a survey of 12,344 U.S. college students and 6,729 Canadian college students, Kuo, Adlaf, Lee, Gliksman, Demers, and Wechsler (2002) report that alcohol use is more common among Canadian than U.S. students, but heavy drinking (five or more drinks in a row for males, four or more for females) is significantly higher among U.S. students than Canadian students. Is this an example of a survey research design?
In Colorado, there is a large group of deer that spend their summer months in a region on one side of a highway and survive the winter months in a lower region on the other side. To determine if the highway has disturbed deer migration to the winter feeding area, the following data were gathered on a random sample of 10 wilderness districts in the winter feeding area. Row B represents the average January deer count for a 5-year period before the highway was built, and row A represents the average January deer count for a 5-year period after the highway was built. The highway department claims that the January population has not changed. Test this claim against the claim that the January population has dropped. Use a 5% level of significance. Units used in the table are hundreds of deer. (Let d = B − A.)

In an experiment with the effect of different feeding on sheep fertility, two feed categories were examined, A and B. 192 rivers were given feed category A and 190 were given feed category B. The following number of monocotyledonous and dicotyledonous sheep were obtained in each category: Feed category A Feed category B Monocotyledonous 60 82 Dicotyledonous 132 108 Examine with an appropriate hypothesis test whether there is a difference in fertility by feed category.
At a TV assembling facility, the Quality Assurance (QA) department tested a random selection of 500 TV's assembled in March. The tested TV's had an average retail price of $475, 2.4% had some type of defect, and 7 did not power up at all. The plant manager compared that to the total 6753 of TV's that were assembled during the month of March. They had an average retail price of $395 , 3.2% had been reported defective by customers, and did not power up at all. For the QA department's tests, identify the population and the sample. Choose whether each number described below is a parameter or a statistic for the QA department's tests. Number Parameter Statistic The 7 TV's of the random selection of 500 TV's that did not power up at all The 2.4% of the random selection of 500 TV's found to be defective The average retail price of $395 of all the TV's assembled during the month of March
In a survey, respondents were asked to disclose their political affiliation (Democrat, Independent, Republican) and also answer the question "Would you be willing to pay higher taxes if the tax revenue went directly toward deficit reduction?" Create a contingency table and determine whether the results suggest there is an association between political affiliation and willingness to pay higher taxes to directly reduce the federal debt. Use the alpha0.05 level of significance. Political Affiliation Willing to pay higher taxes? Political Affiliation Willing to pay higher taxes?

The minister of information proposed that Itheku newspaper should increase its news coverage. This was proposed to enhance free flow of information to the rural areas. Also, the newspaper would be carrying information about the Covid-19 pandemic to enlighten the public on the severity of the virus. An Itheku daily newspaper selected a simple random sample of 1500 readers from their list of 20000 subscribers. They asked whether the paper should increase its coverage of local news. Thirty - five percent of the sample did not support the idea of more local news coverage. What is 98.5% confidence interval for the proportion of readers who would like more coverage of local news?
A school psychologist is interested in whether going to nature school, where children spend their day outside working with nature, versus public school has an effect on children's empathy toward their peers. A national survey of public schools found that, on a scale from 1 to 10, the average empathy among all children in public schools was 5 (u = 5.00). The school psychologist randomly selects 4 children from a nature school, measures their empathy toward their peers, and obtains the following scores: 10, 9, 10, 7 Using the appropriate hypothesis test and the six steps of hypothesis testing, see what the school psychologist should conclude about the difference in empathy between children who attend nature school versus children who attend public school. 1. What is the appropriate test to use ? 2. List the test's assumptions You do NOT have to test the assumptions. 3. What are the null and alternative hypotheses ? 4. Construct a sampling distribution of means representing the null…

Researchers investigated the possible beneficial effect on heart health of crinking black tea and whether adding mikk to the tea reduces any possible benefit Tiventy-four volunteers Were randomly assigned to one of three groups Every day for month; participants in group drank twvo cups ofhot black tea without mikk; participants in group drank two cups of hot black tea with milk; and participants in group drank twvo cups ofhot water but no tea At the end of the month the fesearchers measured the change in each of the participants heart health. Is it reasonable to zeneralize the study beyond the 24 participants? Explain why or why not.
