An industrial/organizational psychologist wants to improve worker productivity for a client firm, but first he needs to gain a better understanding of the life of the typical white-collar professional.

One of the survey questions was, “How many hours do you work at your job on a typical workday?” For the subsample of legal professionals (n = 250), the mean response was M = 9.0 hours, with a sample standard deviation of s = 10.4 hours. The estimated standard error is sMM = . Use the following Distributions tool to develop a 99% confidence interval estimate of the mean number of hours legal professionals work on a typical workday. The psychologist can be 99% confident that the interval from to includes the unknown population mean µ. Normally the psychologist will not know the value of the population mean.

Question

An industrial/organizational psychologist wants to improve worker productivity for a client firm, but first he needs to gain a better understanding of the life of the typical white-collar professional. Fortunately, he has access to the 2008 Workplace Productivity Survey, commissioned by LexisNexis and prepared by WorldOne Research, which surveyed a sample of 650 white-collar professionals (250 legal professionals and 400 other professionals).

One of the survey questions was, “How many hours do you work at your job on a typical workday?” For the subsample of legal professionals (n = 250), the mean response was M = 9.0 hours, with a sample standard deviation of s = 10.4 hours.

The estimated standard error is sMM = .

Use the following Distributions tool to develop a 99% confidence interval estimate of the mean number of hours legal professionals work on a typical workday.

The psychologist can be 99% confident that the interval from to includes the unknown population mean µ.

Normally the psychologist will not know the value of the population mean. But consider the (unrealistic) scenario that a census of legal professionals is conducted. The census reveals that the population mean is μ = 11.6.

How would the psychologist most likely react to the news?

The psychologist would not be surprised that μ = 11.6, because that value is inside the confidence interval.

The psychologist would not be surprised that μ = 11.6, because that value is outside the confidence interval.

The psychologist would be surprised that μ = 11.6, because that value is outside the confidence interval.

The psychologist would be surprised that μ = 11.6, because that value is inside the confidence interval.
