Solve the following problems and show your complete solutions. Draw the normal curve then shade the needed area and indicate the z-value. 1. Given that x is a normally distributed random variable with a mean of 50 and a standard deviation of 5, find the following: e. P(37 < x < 48) f. P(55 < x < 62) g. P(43 < x < 67) h. P(33 < x < 70) P(x > 55) b. Р(x < 40) а. P(x > 45) d. P(x < 65) С.
