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 work-related emails do you receive during a typical workday?" For the subsample of legal professionals (n = 250), the mean response was M = 36.7 emails, with a sample standard deviation of s = 21.2 emails. The psychologist can be 99% confident that the interval from [missing values] to [missing values] 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 = 41.2. How would the psychologist most likely react to the news? The psychologist would be surprised that μ = 41.2 because that value is outside the confidence interval. The psychologist would not be surprised that μ = 41.2 because that value is outside the confidence interval. The psychologist would be surprised that μ = 41.2 because that value is inside the confidence interval. The psychologist would not be surprised that μ = 41.2 because that value is inside the confidence interval.
