Consider testing Upper H 0 : mu equals 20H0: μ=20 against Upper H Subscript a Baseline : mu less than 20Ha: μ<20 where muμ is the mean number of latex gloves used per week by all hospital employees, based on the summary statistics nequals=4444, x overbarxequals=19.219.2, and sequals=11.211.2. Compute the p-value of the test.
Use the t-distribution and the given sample results to complete the test of the given hypotheses. Assume the results come from random samples, and if the sample sizes are small, assume the underlying distributions are relatively normal. Test Upper H Subscript 0 Baseline : mu Subscript 1 Baseline equals mu Subscript 2 vs Upper H Subscript a Baseline : mu Subscript 1 Baseline not-equals mu Subscript 2 using the sample results x Overscript bar EndScripts Subscript 1 Baseline equals 15.3,...
In a test of Upper H 0: mu=100 against Upper H Subscript a: mu not equals100, the sample data yielded the test statistic z=2.24. Find the Upper P-value for the test.
Data were collected on the annual mortality rate (deaths per 100,000) for males in 61 large towns in England and Wales. The data set also notes for each town whether it was south or north of Derby. The summary statistics are given below. Is there a significant difference in mortality rates in the two regions? Answer parts a and b. Assume a significance level of alphaequals0.05.

Researchers wanted to determine if the psychological profile of healthy children was different than for children suffering from recurrent abdominal pain? (RAP) or recurring headaches. A total of 210 children and adolescents were studied and their psychological profiles were graded according to a child behavior checklist. Children were stratified in two age? groups: 4 to 11 years and 12 to 18 years. The results of the study are summarized in the accompanying table. Complete parts ?(a) through? (f) below. n...
