A researcher used a sample of n = 50 individuals to determine whether they are any preferences between two new designs for a smart phone (iphone vs samsung) depending on whether they have a PC or Mac computer. If the data produce a chi-square statistic of χ2 = 7.00 what decision should the researcher make? a.There is a significant preference at both α = .05 and α = .01. b.There is no significant preference at α = .05 but there is at α = .01. c.There is a significant preference at α = .05 but not at α = .01. d.There is no significant preference at either α = .05 or α = .01.

A sample of thirty people is obtained and each person taste three brands of instant coffee and identifies his or her preference. The resulting observed frequency data are as follows: Brand X Brand Y Brand Z 5 14 11 A researcher wants to use these data to test for preferences among the three brands. State the hypotheses and find the expected frequencies for the chi-square test if the researcher expects an equal proportion to fall within each group. Consumer data show that ten years ago, “Brand X” was preferred by 20% of the population, “Brand Y” was preferred by 40% of the population, and “Brand Z” was preferred by 40% of the population. A researcher wants to use these data to test whether there has been a significant change in preferences during the past ten years. State the hypotheses and find the expected frequencies for this chi-square test. Compute two goodness-of-fit hypothesis tests—first using the expected…
The records of a light bulb manufacturer show that, when the manufacturing machinery is working correctly, the defect rate (due to imperfections in the material used) is 1%. The manufacturer's control department periodically tests samples of the bulbs, and when 1.5% or more are defective, they call repair technicians for service.The control department is going to take a random sample of 4400 light bulbs. Let p be the proportion of defective light bulbs in the sample assuming the machinery is working correctly. Answer the following.
A potato chip company produces a large number of potato chip bags each day and wants to investigate whether a new packaging machine will lower the proportion of bags that are damaged. The company selected a random sample of 150 bags from the old machine and found that 15 percent of the bags were damaged, then selected a random sample of 200 bags from the new machine and found that 8 percent were damaged. Let pˆOp^O represent the sample proportion of bags packaged on the old machine that are damaged, pˆNp^N represent the sample proportion of bags packaged on the new machine that are damaged, pˆCp^C represent the combined proportion of damaged bags from both machines, and nOnO and nNnN represent the respective sample sizes for the old machine and new machine. Have the conditions for statistical inference for testing a difference in population proportions been met? No, the condition for independence has not been met, because random samples were not selected. A No, the…
A researcher used a sample of n = 50 individuals to determine whether there are any preferences between two new designs for a smartphone. If the data produce a chi-square statistic of X^2 = 6.00, what decision should the researcher make (indicate df and decisions with a=.05 and a =.01 by reporting critical values)
Suppose that in a study of 35 million HPV shots examined, the shots were followed in time by 14,000 serious ailments and 32 confirmed deaths. However, suppose in examining a randomly selected control group of 35 million non-vaccinated people of the same age at a particular time A, 0.0413% developed a serious ailment soon after time A, and 0.000089% died soon after time A. What does the comparison of two groups tell us? What are the percentages in the vaccinated group (serious ailments and confirmed deaths), and how to they compare to the nonvaccinated group? Hint: compute the percentages for serious ailments (14,000/35,000,000) and confirmed deaths (32/35,000,000) for the vaccinated group. Compare with the control group. Notice % above. (0,0413% and 0.000089%) Answer here. What can we conclude with high probability, if this comparison between vaccinated and non-vaccinated groups was done many times with the same basic results? Answer here. Can we absolutely rule out that the…

In a breeding experiment, chicken with white feathers, small comb were mated and the offspring categories white feathers, small comb (WS), white feathers. large comb (WL), dark feathers, small comb (DS) and dark feathers, large comb (DL) were expected to follow the ratio 9:3:3:1 the researcher observed that there were 100 WS, 32 WL, 40 DS and 20 DL offspring.

A researcher has developed three different designs for a computer keyboard. A sample of n=60 participants is obtained, and each individual tests all three keyboards and identifies his or her favorite. The frequency distribution of the preferences is as follows: DESIGN A DESIGN B DESIGN C n=60 23 12 25a. What is the df value for the chi-square statistic?b. Assuming that the null hypothesis states that there are no preferences among thethree designs, find the expected frequencies for the chi-square test
Suppose it was found that in a random sample of 200 individuals who were underweight (defined as having a BMI of under 18.5), 8 of them were hospitalized with COVID-19. Of a corresponding group of 400 individuals who were classified as severely obese (defined as having a BMI of at least 45.0), 32 were hospitalized with COVID-19. (a) What are the two sample proportions (to 4 decimal places)? (b) What is the difference between the two sample proportions (to 4 decimal places)? (c) If you were testing whether the probability of being hospitalized with COVID-19 differed between the population of underweight individuals and the population of severely obese individuals, what would be your null hypothesis, either in words or in mathematical terms?
