Last year, during an investigation of the time spent reading e-mails on a daily basis, researchers found that on Monday the average time was 50 minutes. Office workers claim that with the increased spam and junk mail, this time has now increased. To conduct a test, a sample of 25 employees is selected with the following results: sample mean = 51.05 minutes and sample standard deviation = 14.2 minutes. What is the critical value for ? = .05 to test the hypotheses. Assume the time spent reading e-mails is normally distributed. Set up the problem. Calculate the test statistic. State your conclusion. Reject/Fail? Based on your decision about the hypothesis testing what kind error is possible? Type 1 or Type 2

A newborn baby has extremely low birth weight if it weighs less than 1000 grams. A study of the health of such children in later years examined a random sample of 219 children. Their mean weight at birth was 810 grams. This sample mean is an unbiased estimator of the mean weight m in the population of extremely low birth weight babies. This means that:a. when the sample is a simple random sample from the population, the mean of the sampling distribution of the sample mean is the same as the population mean.b. as we take larger and larger samples from this population the sample mean, x-bar, will get closer and closer to the population mean.c. in many samples from this population, the many values of x-bar will have a distribution that is close to Noral.d. in many births from this population the many values of x-bar will be equal to m.
