Question 862602: μ = 120
σ = 9.75
N = 1000
population Normal
If one person is selected at random from the population in the table, calculate the probability of a blood pressure greater than 136. Would you consider this result unusual - why or why not?

Hi

μ = 120,  σ = 9.75,  N = 1000

P(x >136) = 1 - P(z < %28136-120%29%2F%289.75%29%29)= 1 - P(z < 1.64) = 5.05%
