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. If there is clear evidence that this proportion is less than 0.10, she will accept the shipment. To reach a decision, she will test the hypotheses Ho: p=0.10 versus H:p <0.10. To do so, she selects a simple random sample of 150 potatoes from the more than 3000 potatoes on the truck. Only 8 of the potatoes sampled are found to have major defects. a a) Apply the large sample z-test to test the above hypotheses. Report the p-value Should the inspector accept the shipment? Use a significance level of 0.05. State your conclusion in plain language. (Top-Hat) b) Apply the exact Binomial test, find the p-value and compare it to the p-value you found in
Which is the correct conclusion of the large A At 5% significance level, there is not enough evidence that the proportion of defective potatoes in the batch is less than 10%. B At 5% significance level, there is enough evidence that the proportion of defective potatoes in the batch is less than 10%. C At 5% significance level, there is enough evidence that the proportion of defective potatoes in the batch is greater than 10%.
Does your conclusion change if you use the exact Binomial test? А Yes B B No
