Complete Question

 An inspector inspects large truckloads of potatoes to determine the proportion p in the shipment with major defects prior to using the potatoes to make potato chips. Unless there is clear evidence that this proportion, p, is less than 0.10, he will reject the shipment. He will test the hypotheses

H0: p = 0.10, Ha: p < 0.10.

He selects an SRS of 100 potatoes from the over 2000 potatoes on the truck. Suppose that 6 of the potatoes sampled are found to have major defects. The P-value of this test is.......

Group of answer choices

A 0.4082

B 0.0912

C less than 0.002

D 0.0400

Correct option is B

Step-by-step explanation:

From the question we are told that

      The null hypothesis is

   The alternative hypothesis is  

The sample size is  n =  100

The probability  of getting  a potatoes that is not defected is   

The probability of getting a defected potatoes is  q = 1-p

The proportion of defected potatoes is mathematically evaluated as

The test statistics is evaluated as

substituting values

The p-value is  0.0912 from the z-table (you can also use excel formula )
