A national health survey of 2010-2012 estimated the mean serum cholesterol level for Canadian females aged 20-29 years to be 4.7 mmol/L.  The estimated standard deviation was approximately 1.0 mmol/L.  Use thee estimates as the mean (μ) and standard deviation (σ) for the Canadian population. If a simple random sample of size 60 is drawn from this population, find the probability that the sample mean serum cholesterol level will be: Between 4.4 and 4.9, Greater than 4.9 and Below 4.4
