Assume that x has a normal distribution with the specified mean and standard deviation. Find the indicated probability. (Round your answer to four decimal places.)
μ = 28; α = 3.6
P(x ≥ 30) = _______
mean = 28
standard deviation = 3.6
P(x >= 30) = ?
consider,
P(x >= 30) = P((x-mu)/s >= (30 - 28)/3.6)
= P(z >= 0.5556)
= 0.2892422 [since from z table]
= 0.2892
P(x >= 30) = 0.2892
