Let X∼N(μ,σ2)X \sim N(\mu, \sigma^2)X∼N(μ,σ2). If P(X≤50)=0.95P(X \le 50) = 0.95P(X≤50)=0.95, what is the relationship between μ\muμ and 50?
50=μ+1.645σ50 = \mu + 1.645\sigma50=μ+1.645σ
50=μ+1.96σ50 = \mu + 1.96\sigma50=μ+1.96σ
50=μ−1.645σ50 = \mu - 1.645\sigma50=μ−1.645σ
50=μ+2.33σ50 = \mu + 2.33\sigma50=μ+2.33σ
