question 15

Short Answer

Two independent random samples of 25 observations each are drawn from two normal populations. The parameters of these populations are:  Population 1: μ=150,σ=50. Population 2: μ=130,σ=45.\begin{array} { | l | l | } \hline \text { Population 1: } & \mu = 150 , \sigma = 50 . \\\hline \text { Population 2: } & \mu = 130 , \sigma = 45 . \\\hline\end{array} Find the probability that the mean of sample 1 will exceed the mean of sample 2.
