Traumatic Brain Injury (TBI) is a significant health problem. TBI is caused by impacts to the head that might occurduring contact sports, motor vehicle accidents, and similar events. TBI is known to produce cognitive impairments and reductions in brain volume. In a recent, repeated-measures study on TBI, Zagorchev et al.(2016) observed that the size of the amygdala among mild TBI patients was reduced at 12 months after injury, relative to two months after injury. Suppose that a researcher is interested in replicating and extending this observation. She recruits n=8 participants with mild TBI and records the volume of a brain region at 2 months and again and again at 12 months. Her data are listed below
a.) Test the hypothesis that volume of the brain region changed between 2 & 12 months. Use α=0.05, two-tailed
b.) Compute the 80% confidence interval for the mean change in attention span for the population
In a study examining the effects of alcohol on reaction time,Liguori and Robinson (2001) found that even moderate alcohol consumption significantly slowed response time to an emergency situation in a driving simulation. In a similar study,reasearchers measured reactio 30 minutes after participants consumed one 6- ounce glass of wine.Again, they used a standardized simulation task for which the regular population averages of population= 4000msec. The distributions of reactions times is approximately normal with deriavance=40. Assume that the researcher obtained a sample mean of M=422 for the n= 25 participants in the study.
A) are the data sufficient to conclude that alcohol has a significant effect on reaction time? Use a two tailed test with a=.01
B) Do the data provide evidence that the alcohol significantly increased reaction time?
C) Compare Cohen's d to estimatethe size of the effect
Stressed-Out Bus Drivers. Previous studies have shown that urban bus drivers have an extremely stressful job, and a large proportion of drivers retire prematurely with disabilities due to occupational stress. In the paper, “Hassles on the Job: A Study of a Job Intervention With Urban Bus Drivers” (Journal of Organizational Behavior, Vol. 20, pp. 199–208), G. Evans et al. examined the effects of an intervention program to improve the conditions of urban bus drivers.Amongother variables, the researchers monitored diastolic blood pressure of bus drivers in downtown Stockholm, Sweden. The data, in millimeters of mercury (mm Hg), on the WeissStats site are based on the blood pressures obtained prior to intervention for the 41 bus drivers in the study. Use the technology of your choice to do the following.
a. Obtain a normal probability plot, boxplot, histogram, and stemand-leaf diagram of the data.
b. Based on your results from part (a), can you reasonably apply the one-mean t-test to the…

- An experiment was conducted to compare the alcohol content of soy sauce on two different production lines. Production was monitored eight times a day. The data are shown here. Production line 1 0.38 0.37 0.39 0.41 0.38 0.39 0.40 0.39 Production line 2 0.48 0.39 0.42 0.52 0.40 0.48 0.52 0.52 Assume both populations are normal. It is suspected that production line 1 is not producing as consistently as production line 2 in terms of alcohol content. Using the 0.05 level of significance, can conclude that the population standard deviations for the alcohol content of these two types of production lines could be the same.arrow_forwardWhen investigating the relationship between aerobic exercise capacity (as measured by VO2max, a continuous variable) and serum concentration of vitamin D, the authors of this study report a Pearson correlation coefficient estimate of r = 0.23 with a p-value of <0.01.
