A study of hand reaction time among Indian hockey players is conducted. The purpose is to compare visual with auditory reaction time. Visual reaction time is measured by noting the time needed to respond to a light signal; auditory reaction time is the time needed to respond to a click of an electric switch. These times are noted for 15 subjects.

Is there evidence, based on the sign test, to conclude that the visual reaction time differs significantly from the auditory reaction time?

The following are reaction time results for catching an object, with the dominant hand, that is dropped 2 feet above the hand. The two groups are A (the experimental group) and B (the control group). Experimental and Control groups are the same as listed at the beginning of the description of the study. Use the p-value approach, with a-level = .05. N1: mean = .22 seconds; Standard Deviation = .034 seconds N2: mean = .203 seconds; Standard Deviation = .041...

A study conducted at a major university indicates that the tendency among undergraduates to seek the assistance of helper differs by ethnic group. You select 25 subjects each from two different ethnic groups or business majors and count the number who sought help. In ethic group A, 11 sought out helpers at some point. In ethnic group B, 17. What are the frequency expected values for each group? Do results support the earlier study? What does the alternate hypothesis suggest...

A researcher at a medical college conducted a study of 60 randomly selected male soccer players and concluded that frequently "heading" the ball in soccer lowers players' IQs. The soccer players were divided into two groups, based on whether they averaged 10 or more headers per game. Mean IQs were reported in the article, but the sample sizes and standard deviations were not given. Suppose that these values were as given in the accompanying table. n Sample Mean Sample sd...

A 1980 study was conducted whose purpose was to compare the indoor air quality in offices where smoking was permitted with that in offices where smoking was not permitted. Measurements were made of carbon monoxide (CO) at 1:20 p.m. in 36 work areas where smoking was permitted and 36 work areas where smoking was not permitted. In the sample where smoking was permitted, the mean CO = 11.6 parts per million (ppm) and the standard deviation CO = 7.3 ppm....

A study is conducted to look at the time students exercise in average. In a random sample of 115 students, a researcher finds that the mean time students exercise is 11.3hrs/month with a standard deviation of 6.43hrs/month. Using the Critical Value Methodand a 5% significance level, can a researcher conclude that in average students exercise less than 15 hours per month?

A customer satisfaction study was conducted among patients from a number of healthcare providers. The questionnaire included items assessing patient expectations and perceptions of service provider performance across several relevant elements. One respondent appeared to have read the directions and the researcher presumed she accurately responded to the first of the items on the rating scale. She then proceeded to write down replies to open-ended responses. The respondent, a 94 year old woman was doing her best to answer all...
