Adjusting the probability statement P(34.5 ≤ x ≤ 40.5) to the standard normal variable resulted in P(0.92 ≤ z ≤ 2.14). Recall that the normal probability table gives area under the curve to the left of a given z
value.
Use the table to find P(0.92 ≤ z ≤ 2.14), the probability that between 35 and 40 adults in the group smoke, rounding the result to four decimal places.
P(0.92 ≤ z ≤ 2.14) = P(z ≤ 2.14) - P(Z ≤ 0.92)
= 0.9838 -
