Answer to relevant QuestionsDraw the normal curve with the parameters indicated. Then ﬁnd the probability of the random variable X. Shade the area that represents the probability. µ = 50, σ = 6, P(X > 55) According to major league baseball rules, the ball must weigh between 5 and 5.25 ounces. A factory produces baseballs whose weights are approximately normally distributed, with mean 5.11 ounces and standard deviation ...Draw a standard normal curve and shade the area to the right of z = 2.04. Then ﬁnd the area of the shaded region. A continuous random variable X is uniformly distributed with 10 ≤ X ≤ 50. (a) Draw a graph of the uniform density function. (b) What is P(20 ≤ X ≤ 30)? (c) What is P(X < 15)? Draw a normal curve with µ = 30 and σ = 10. Label the mean and the inﬂection points.
