As a hospital administrator of a large hospital, you are concerned with the absenteeism among nurses aides. The issue has been raised by registered nurses, who feel they often have to perform work normally done by their aides. To get the facts, absenteeism data were gathered for the last three weeks, which is considered a representative period for future conditions. After taking random samples of 64 personnel files each day, the following data were produced. Because your assessment of absenteeism is likely to come under careful scrutiny, you would like a type I error of only 1%. You want to be sure to identify any instances of unusual absences. If some are present you will have to explore them on behalf of the registered nurses. a) Design a P chart. The upper control limit is blank and the lower control limit is blank. (Enter your responses rounded to three decimal places. If your answer for the lower control limit is negative, enter this value as 0.)

As the director of the local Boys Club, you have claimed for years that membership in your club reduces juvenile delinquency. Now a cynical member of your funding agency has demanded proof of your claim. Random samples of members and non-members are gathered and interviewed with respect to their involvement in delinquent activities. Each respondent is asked to enumerate the number of delinquent acts they engaged in over the last year. The average numbers of admitted acts of delinquency are reported below. What can you tell the funding agency? MEMBERS NON-MEMBERSmean=10.3 mean=12.3s=2.7 s=4.2N=50 N=55

To help assess the health risks of second-hand smoke, the levels of cotinine (a metabolite of nicotine) were measured in mmol/l in the urine of seven subjects prior to exposure to second-hand smoke and shortly after a two-hour exposure to secondary cigarette smoke. Did the exposure significantly increase the cotinine level? What will be the appropriate statistical analysis to use in this problem? a. z-Test for Comparing Two Means from Independent Populations b. t-Test for Comparing Two Means when the Samples are Dependent c. z-test for comparing the difference between two proportions d. t-Test for Comparing Two Means from Independent Samples e. F-test in Comparing the Difference Between Two Variances
A researcher believes that children who attend elementary school in a rural setting have lower obesity rates then children who attend elementary school in an urban setting. The researcher collects a random sample from each population and records the proportion of children in each sample who are clinically obese. The data is summarized in the table below. Assume that all conditions for proceeding with a two-sample test have been met. Find the z-statistic (rounded to the nearest hundredth) and p-value (rounded to the nearest thousandth) for this hypothesis test. Using a 5% significance level, state the correct conclusion regarding the null hypothesis H0: prural = purban. a) z = -1.95, p = 0.026. There is sufficient evidence to reject the null hypothesis. b) z = -1.85, p = 0.032. There is sufficient evidence to accept the null hypothesis. c) z = -1.95, p = 0.026.
