Determine point estimate for mean number of weekly hours

Reference no: EM13137455

A study was conducted in order to estimate μ, the mean number of weekly hours that U.S. adults use computers at home. Suppose a random sample of 81 U.S. adults gives a mean weekly computer usage time of 8.5 hours and that from prior studies, the population standard deviation is assumed to be σ = 3.6 hours.

Based on this information, what would be the point estimate for μ?
