Question

Sleep apnea: Sleep apnea is a disorder in which there are pauses in breathing during sleep. People with this condition must wake up frequently to breathe. In a sample of 433 people aged 65 and over, 107 of them had sleep apnea. Find a point estimate for the population proportion of those aged 65 and over who have sleep apnea. Round the answer to three decimal places. Construct a 99.5% confidence interval for the proportion of those aged 65 and over who have sleep apnea. Round the answer to three decimal places. A 99.5% confidence interval for the proportion of those aged 65 and over who have sleep apnea is __< p < __ In another study, medical researchers concluded that more than 11% of elderly people have sleep apnea. Based on the confidence interval, does it appear that more than 11% of people aged 65 and over have sleep apnea? Explain. Since all of the values in the confidence interval are less than or greater than 0.11, the confidence interval does or does not contradict the claim.
