Answer to relevant QuestionsDraw a normal curve with µ = 50 and σ = 5. Label the mean and the inﬂection points. The lengths of human pregnancies are normally distributed with µ = 266 days and σ = 16 days. (a) The ﬁgure represents the normal curve with µ = 266 days and σ = 16 days. The area to the right of x = 280 is 0.1908. ...Determine the area under the standard normal curve that lies to the right of (a) z = -3.49 (b) z = -0.55 (c) z = 2.23 (d) z = 3.45 Find the indicated areas. Be sure to draw a standard normal curve and shade the area that ...z0.15 Find the value of za . Assume that the random variable X is normally distributed, with mean µ = 50 and standard deviation σ = 7. Compute the following probabilities.
