b.) 0.9706

Step-by-step explanation:

Given : Proportion of  the 5,000 payroll vouchers issued since January 1, 2000, have irregularities : p=0.10

Now , using standard normal z-value table , we have

The probability that Pinky's random sample of 200 vouchers will have a sample proportion greater than .06 will be :-

  [By using z-value table]

Hence, the  probability that Pinky's random sample of 200 vouchers will have a sample proportion greater than .06 is b.) 0.9706.
