What's the probability, the sample mean for the 16 hour long periods is less than 47?
The outside “clip‐on” lanes of the Auckland Harbour Bridge are to be closed to heavy vehicles, due to
structural damage.
Suppose in order to understand the amount of cargo being transported over the bridge that Land
Transport monitored the traffic for 16 randomly selected one hour periods. The number or trucktrailers
were counted for each one hour period and the sample mean x calculated.
Assume the number of truck‐trailers crossing the bridge per hour is normally distributed with a mean
50 and standard deviation of 8.

Extremely helpful in confirming my analysis of problems. Thank you
