Answer to relevant Questions(a) Draw a normal curve with µ = 20 and σ = 3. (b) Shade the region that represents P(22 ≤ X ≤ 27) and ﬁnd the probability. 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)? One graph in the ﬁgure represents a normal distribution with mean µ = 10 and standard deviation σ = 3. The other graph represents a normal distribution with mean µ = 10 and standard deviation σ = 2.
