Question

Step 5 #1 6.6 So, converted to a z interval, we wish to find P(1.58 < z < 2.09).

Recall that since the z value is between two different values, we will need to subtract the table areas for z1 = 1.58 from the table area for z2 = 2.09.

Use this table to determine P(z < 1.58) and P(z < 2.09). Substitute these values into the formula to find the probability. (Round your answer to four decimal places.)

P(1.58 < z < 2.09) = P(z < 2.09) − P(z < 1.58) =

Answer 1

To find the probability, calculate the z-score and look up the z-score in the z-table under the z-column.

Step-by-step explanation:

The z-table shows that the area to the left of z is 0.6554. Subtracting this area from 1 gives 0.3446. Then, find P(x > 65).
