Now, we can compute the z-score and get z = (0.65 – 0.75) / 0.0433 = -2.31. Then, we use a z-table to find P(Z < -2.31) = 0.0104. 38. B Note that we are taking a random sample of 143 adult males. Since this sample size is larger than 30, we can use the Central Limit Theorem and conclude that average weight is approximately normally ...
