A) If a normal distribution has a mean µ = 40 and a standard
deviation σ = 2, what value of x would you expect to find 2
standard deviations below the mean
B) If a normal distribution has a mean µ = 70 and a variance σ2
= 16, what value of x would you expect to find 2.5 standard
deviations above the mean?
C)If a sample yields a mean xmean = 44 and we know that the sum...
