Question description

Reports from a new system set up to monitor Internet use by company employees indicate that 145 out of a random sample of 1100 employees at a corporation accessed internet sites that were clearly not related to their jobs over the last week. On average, employees who accessed non job related sites spent 4.8 hours per week at such sites with a standard deviation of 2.1 hours
a. Give a 95% confidence interval for the percentage of employees at the corporation who access non-job related sites.
b. Briefly explain in one short sentence how to interpret this interval.

c. Statistics show that about 103 of people nationwide access non-job related sites at work. Is this company really any different from the national statistics?
d. Can we say that roughly 953 of people at this company spent in the range of 4.8 hours plus or minus 4.2 hours on non job-related web sites?
