USE THE 8-STEP HYPOTHESIS TESTINGIn the study by Silver and Aiello (A-4) cited in Example 12.4.2, a secondary objective was todetermine if the frequency of falls was independent of wheelchair use. The following table gives thedata for falls and wheelchair use among the subjects of the study.FallersNonfallersYes6218Wheelchair UseNo12132Source: J. K. Silver and D. D. Aiello, "Polio Survivors: Falls andSubsequent Injuries," American Journal of Physical Medicine andRehabilitation, 81 (2002), 567-570.Do these data provide sufficient evidence to warrant the conclusion that wheelchair use and falling arerelated?

Booted Eagles. The rare booted eagle of western Europe was the focus of a study by S. Suarez et al. to identify optimal nesting habitat for this raptor. According to their paper “Nesting Habitat Selection by Booted Eagles (Hieraaetus pennatus) and Implications for Management” (Journal of Applied Ecology, Vol. 37, pp. 215–223), the distances of such nests to the nearest marshland are normally distributed with mean 4.66 km and standard deviation 0.75 km. Let Y be the distance of a randomly selected nest to the nearest marshland. Determine and interpret a. P(Y >5). b. P(3 ≤ Y ≤ 6).
A researcher wants to examine the effect of daily mental exercises on cognitive performance of people in early stages of Alzheimer's disease. She enrolled to her study n = 16 patients diagnosed with the early stage of Alzheimer's disease and all participants conducted daily mental exercises for a month. At the end of the program all enrolled patients took the MMSE test (i.e., Mini-Mental State Examination). The results show that the sample mean on the MMSE test was M = 23.6 with the standard deviation, s = 7. It is known that the MMSE mean in the population of patients with early Alzheimer's disease is µ = 20. Do these data show a significant effect of daily mental exercises on cognitive performance in early stages of Alzheimer's disease?
38. The drug diethylstilbestrol was used for years by women as a nonsteroidal treatment for pregnancy maintenance, but it was banned in 1971 when research indicated a link with the incidence of cervical cancer. The article "Effects of Prenatal Exposure to Diethylstilbestrol (DES) on Hemi- spheric Laterality and Spatial Ability in Human Males" (Hormones and Behavior, 1992: 62-75) dis- cussed a study in which ten males exposed to DES and their unexposed brothers underwent various tests. This is the summary data on the results of a spatial ability test: exposed mean = 12.6 unexposed mean = 13.8 standard error of difference = = 5 Vn Does DES exposure appear to be associated with reduced spatial ability? State and test the appropri- ate hypotheses using a = .05. Does the conclusion. change if a = .01 is used?
Is there an association between daily screen time and exercise habits in high school students? Mia selects a random sample of 123 high school students and categorizes them into 1 of 3 categories of screen time and whether they exercise. She would like to determine if there is convincing evidence of an association. Let = 0.05. What are the hypotheses for this test? H0: There is an association between daily screen time and exercise habits in high school students.Ha: There is no association between daily screen time and exercise habits in high school students.H0: There is no association between daily screen time and exercise habits in high school students.Ha: There is an association between daily screen time and exercise habits in high school students.H0: There is no difference in the distribution of daily screen time and exercise habits in high school students.Ha: There is a difference in the distribution of daily screen time and exercise habits in high school students.H0: There is a…
A bank conducts a survey in which it randomly samples 400 of its customers. The survey asks the customers which way they use the bank the most: (1) interacting with a teller at the bank, (2) using ATM's or (3) using the bank's online banking service. It also asks their level of satisfaction with the service they most often use (on a scale of 0-10 with 0= very poor and 10=excellent). Does mean satisfaction differ according to how they most use the bank? a) Identifying notation, state the null hypothesis and alternative hypothesis for conducting an ANOVA with data from the survey. b) Report the df values for this ANOVA. Above what F statistic values give a P=value below 0.05? c) For the data, F=0.46 and the P-value equals 0.63. what can you conclude? d)What were the assumptions on which the ANOVA was based? Which assumption is the most important? e) based on answer C, do you think it is necessary to conduct Tukey's multiple comparisons? Why or why not?
one- Oishi and Schimmack (2010) report that people who move from home to home frequently as children tend to have lower than average levels of well-being as adults. To further examine this relationship, a psychol- ogist obtains a sample of n = 12 young adults who each experienced 5 or more different homes before they were 16 years old. These participants were given

Does buttered toast fall face down? Data was collected to test this. 40 slices of toast (each with butter on one side) were dropped (from the same height). 24 slices (60%) landed buttered side down. We would like to use the results of this study to determine if there is statistical evidence that toast tends to land buttered side down more than 50% of the time.
Consider a within-subjects experimental design with two conditions. The experimenter ran both a correlated t test (which is the correct analysis) and (incorrectly) an independent-groups t test. The experimenter found the correlated t test was significant whereas the independent-groups t test was not. The experimenter concluded that this was because the mean difference score across subjects was greater than the difference between the means of the conditions. Is this the correct conclusion? yes no
Indicate whether CPAs in states that have flat state income tax rates work fewer hours per week during tax season compared to the US average. You will want to formally set up H0 and Ha, report either the test statistic (z-value) or p-value, and explain why you either reject or fail to reject your null hypothesis.
A type 2 error occurs when a treatment actually does have an effect on the scores but the effect was not large enough to reject the bill hypothesis. True or false?
