Question

ses A quality control manager thinks that there is a higher defective rate on the production line than the advertised value of p = 0.025. She does a hypothesis test with a significance level of 0.05. Symbolically, the null and alternative hypothesis are as follows: Ho:p=0.025 and Hq:P >0.025. She calculates a p-value for the hypothesis test of defective light bulbs to be approximately 0.067. Choose the correct interpretation for the p-value. Hon ork O A. The p-value tells us that the result is significantly higher than the advertised value using a significance level of 0.05. OB. The p-value tells us that the true population rate of defective light bulbs is approximately 0.067. & T O C. The p-value tells us that the probability of concluding that the defect rate is equal to 0.025, when in fact it is greater than 0.025, is approximately 0.067 lan OD. The p-value tells us that if the defect rate is 0.025, then the probability that she would observe the percentage she actually observed or higher is 0.067. At a significance level of 0.05, this would not be an unusual outcome. nch

Answer 1

The correct option is ID The P-value tells us that if the defects rate is 0.025, then the probability that she would observe the percentage she actually observed or Significance level of 0.05. This would not be an higher is 0.067. At a uhusual outcome.
