Question

Determine the area under the standard normal curve that lies to the left of (a) z 0.72, (b) Z1.24, (c) z 0.56, and (d) z-0.51. (a) The area to the left of z 0.72 is (Round to four decimal places as needed.) (b) The area to the left of z -124 is (Round to four decimal places as needed.) (c) The area to the left of z 0.56 is (Round to four decimal places as needed.) (d) The area to the left of z 0.51 is Round to four decimal places as needed.) Enter your answer in each of the answer boxes Save for Later

Explanation / Answer

From the z table output, the required areas will be:

a) P(z < 0.72) = 0.7642

b) P(z < -1.24) = 0.1075

c) P(z < 0.56) = 0.7123

d) P(z < 0.51) = 0.6950
