Page 3 of 4 ZOOM A research organization has collected data on the prices ($) of microwave ovens in the two different wattage categories as follows: 1000 W 900 W 270 240 245 135 190 160 215 230 250 250 230 200 200 210 11. The test statistic value calculated to test whether the average price of a 900W oven is game as the average price of a 1000W oven is: A. 1.01 B. 1.67 C. 16.7 12. The probability of the event that the standardized test statistic would assume a value as extreme or more extreme than that obtained in question 1 1 is: A. 0.001 B. 0.01 C. 0.12 13 By comparing the probability value (calculated in question 12) to a 5% significance level in a hypothesis test it can be concluded that A: the mean prices of the two types of ovens are about the same values B: the mean prices of the two types of ovens are not about the same values C: no conclusion can be drawn about the mean prices of the two types of ovens 14. The lower bound of the 95% confidence interval for the difference in the population mean prices for the two types of ovens is: A. 0 B. 9 C. 70 15. The upper bound of the 95% confidence interval for the difference in the population mean prices for the two types of ovens is: A: 0 B 9 C. 70 a Test 1 16. The sample prices for 900W microwave ovens are: A. normally distributed with a mean of $203.13 and a standard deviation of $39.36 B. not normally distributed with a mean of $203.13 and a standard deviation of $39.36 f 536.82
