We're interested in the amount of time spent at work by college graduates employed full-time. The standard amount of time spent at work by full-time employees is 40 hours per week. We suspect that the mean number of hours worked per week by college graduates is less than 40 hours and wish to do a statistical test. We select a random sample of 100 college graduates employed full-time and compute the mean number of hours worked per week by the...

Some college graduates employed full-time work more than 40 hours per week, and some work fewer than 40 hours per week. We suspect that the mean number of hours worked per week by college graduates, , is different from 40 hours and wish to do a statistical test. We select a random sample of college graduates employed full-time and find that the mean of the sample is 36 hours and that the standard deviation is 3 hours. Based on this...

A study claims that over 50% of those who suffer from osteoarthritis receive measurable relief from an ingredient produced by a particular species of mussel. To test this claim, the mussel extract is to be given to a group of 8 osteoarthritic patients. If 4 or more of the patients receive relief, we shall not reject the null hypothesis that p=0.5; otherwise, we conclude that p<0.5. (a) Evaluate α,assuming that p=0.5. (b) Evaluate β for the alternative p=0.4.

It seems these days that college graduates who are employed full-time work more than 40-hour weeks. Data are available that can help us decide if this is true. A survey was recently sent to a group of adults selected at random. There were 9 respondents who were college graduates employed full-time. The mean number of hours worked per week by these 9 respondents was 43 hours, with a standard deviation of 9 hours. . Can...

The proportion of college graduates who get jobs by networking after graduation is greater than 0.5, as reported by workforce ed. A sample of 200 college graduates reveal that 85 got jobs by networking after graduation. Use the 10% level of significance to test this claim by determining the following 8. What is your hypothesis? 9 What is your decision rule. 10. Determine the test statistic approximated to the place value as the critical value. 11. What is your conclusion....

It seems these days that college graduates who are employed full-time work more than 40-hour weeks. Data are available that can help us decide if this is true. A survey was recently sent to a group of adults selected at random. There were 15 respondents who were college graduates employed full-time. The mean number of hours worked per week by these 15 respondents was 45 hours, with a standard deviation of 9 hours. Assume that the population of hours worked...

The dean of a college is interested in the proportion of graduates from his college who have a job offer on graduation day. He is particularly interested in seeing if there is a difference in this proportion for accounting and economics majors. In a random sample of 200 of each type of major at graduation, he found that 72 accounting majors and 52 economics majors had job offers. Assume pooled estimate of the population proportion and a level of significance...

Among a simple random sample of 331 American adults who do not have a four-year college degree and are not currently enrolled in school, 48% said they decided not to go to college because they could not afford school. (a) A newspaper article states that only a minority of the Americans who decide not to go to college do so because they cannot afford it and uses the point estimate from this survey as evidence. Conduct a hypothesis test to...
