Find the area of the shaded region for each standard normal curve(a) The shaded region has an area of _____________.(Round to four decimal places as needed.) (b) The shaded region has an area of _____________.(Round to four decimal places as needed.) (c) The shaded region has an area of _____________.(Round to four decimal places as needed. The image contains three graphs, labeled (a), (b), and (c), each depicting a standard normal distribution curve (bell curve) with specific areas shaded in light blue.**(a)**- Graph (a) shows a bell curve with two vertical lines marking the z-scores at approximately -1.45 and 1.69. - The area between these two lines is shaded, indicating the central region of the distribution.**(b)**- Graph (b) depicts a similar bell curve with vertical lines at approximately -1.74 and 1.74.- The shaded regions are outside these lines, representing the tails of the distribution.**(c)**- Graph (c) illustrates another bell curve with lines at approximately -0.39 and 0.39.- The area between these lines is shaded, which shows the central portion of the curve, narrower than in (a).These diagrams could be used to demonstrate the concept of standard deviations and the probabilities associated with different segments of a normal distribution.

The required shaded area under the normal curve is Refer to Standard normal table/Z-table to find the probability of z=1.69 and z=-1.45 to the left of the normal curve. OR Use excel formula "=NORM.S.DIST(1.69, TRUE)" and "=NORM.S.DIST(-1.45, TRUE)" to find the probability. Therefore, the probability isNote that the total area under the normal curve is 1. Therefore required shaded area is 1-area between z=-1.74 and z=1.74. The required shaded area under the normal curve is Refer to Standard normal table/Z-table to find the probability of z=1.74 and z=-1.74 to the left of the normal curve. OR Use excel formula "=NORM.S.DIST(1.74, TRUE)" and "=NORM.S.DIST(-1.74, TRUE)" to find the probability. Therefore, the probability isThe required shaded area under the normal curve is Refer to Standard normal table/Z-table to find the probability of z=0.39 and z=-0.39 to the left of the normal curve. OR Use excel formula "=NORM.S.DIST(0.39, TRUE)" and "=NORM.S.DIST(-0.39, TRUE)" to find the probability. Therefore, the probability is
