Extracted text: Given: The 99% confidence interval for u is: (16.7 , 22.4) Complete the following: According to the observed confidence interval, the null hypothesis is and there is sufficient evidence to claim that the average access time from 21 hours, at 0.01 level of significance. According to the observed confidence interval, we know that: True False 99% of all medical practitioners at Health Care II have access times between 16.7 and 22.4 hours. For every 100 random samples drawn, we expect that 99 of the confidence intervals will contain the population mean. We are 99% confident that u is between 16.7 and 22.4. 99% of all samples should have sample means between 16.7 and 22.4. The probability that u is between 16.7 and 22.4 is 0.99. For every 100 random samples drawn, we expect that 99 of the confidence intervals will contain the sample mean. O O O O O O
