Assuming that x has a normal distribution, find the indicated probability
a) p(40<_x<_47) mean=50, stand.dev.=15 and p(x_>2)mean=3stand.dev.=0.25
b) Find z value and sketch the are described
1) 97.5%of normal curve lies to the left of z
2) Find z such that 95% of standard normal curve lies to the right of z
The solution file is attached.
