Question

Use the standard normal table to find the​ z-score that corresponds to the cumulative area 0.0091. If the area is not in the​ table, use the entry closest to the area. If the area is halfway between two​ entries, use the​ z-score halfway between the corresponding​ z-scores.

Answer 1

we have to find z-score that corro o sponds to the calcware area 0.0091 i.e P(Z <Z) = 0.0091 (1) by using standard normal table. - 2:362) = 0.0091 . (2) comparing (i) & (2) z = - 2.362 :: The z - score that corrospondes to the cumulative area 0.0091 is -2.362 Ans: 2.326 CS Scanned with CamScanner
