Draw a sketch of the sampling distribution for the sample mean time spent by students at the CSB. Remember, the sample size is 70, the true population mean is 1 hour (µ = 1 hour) and
the population standard deviation is 1 (σ = 1). Indicate the area that you are interested in on
this sketch (i. e., the area that includes all ‘samples of size 70 with a sample mean exceeding
1.1 hours’
