The area to the left of z = -1.04. Draw a standard normal curve and shade the area indicated. Then ﬁnd the area of the shaded region. Draw 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) In 1798, Henry Cavendish obtained 27 measurements of the density of Earth, using a torsion balance. The following data represent his estimates, given as a multiple of the density of water. Is it reasonable to conclude that ...(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. Imagine that a friend of yours is always late. Let the random variable X represent the time from when you are supposed to meet your friend until he shows up. Suppose your friend could be on time (x = 0) or up to 30 minutes ...Post your question
