Winston's assembly unit has decided to use a p-Chart with an a risk of 1 % to monitor the proportion of defective metal shafts produced by their production process. The production manager randomly samples 200 metal shafts at 16 successively selected time periods and counts the number of defective metal shafts in the sample. Table Answer How to enter your answer Step 8 of 8: You, acting as the production manager, have concluded that the process is "Out of Control". What is the probability that the process is really "In Control" and you have made a Type I Error? Round your answer to three decimal places. Sample Defects 1 2 3 4 5 6 7 8 9 10 11 9 8 12 12 11 13 7 12 11 11 8 7 Control Chart 12 13 10 14 13 15 7 16 10 Copy Table The average of the selected cell(s) is9.000. Copy Value X

Hypertension It has been found that 26% of men 20 years and older suffer from hypertension (high blood pressure) and 31.5% of women are hypertensive. A random sample of 171 of each gender was selected from recent hospital records, and the following results were obtained. Can you conclude that a higher percentage of women have high blood pressure? Use a = 0.10. Men 44 patients had high blood pressure Women 58 patients had high blood pressure Use p, for the proportion of men with high blood pressure and round all intermediate calculations to at least three decimal places.

OBFW Publishers A state's Division of Motor Vehicles (DMV) claims that 60% of all teens pass their driving test on the first attempt. An investigative reporter examines an SRS of the DMV records for 125 teens; 86 of them passed the test on their first try. A hypothesis test of Ho: P = 0.60 Ha:p # 0.60 where p = the true proportion of teens who pass their driving test on the first attempt using a = 0.05 gives a P-value of 0.0444. A 95% confidence interval for the true proportion of teens who pass the driving test on the first attempt is 0.607 to 0.769. Which is the following statements is not true with regards to the 95% confidence interval provided and the result of the hypothesis test? OA two-sided test only allows us to reject (or fail to reject) a hypothesized value for a particular population parameter. The value 0.60 is not a plausible value because it falls outside the 95% confidence interval. The 95% confidence interval provided gives an approximate set of po's that would not be…
