Sleep apnea is a condition in which the sufferers stop breathing momentarily while they are asleep. This condition results in lack of sleep and extreme fatigue during waking hours. A current estimate is that 23.5 million out of the 312.7 million Americans suffer from sleep apnea, or approximately 7.5%. A safety commission is concerned about the percentage of commercial truck drivers who suffer from sleep apnea. They do not have any reason to believe that it would be higher or lower than the population's percentage. To test the claim that the percentage of commercial truck drivers who suffer from sleep apnea is not 7.5 %, a simple random sample of 476 commercial truck drivers is examined by a medical expert, who concludes that 49 suffer from sleep apnea. Does this evidence support the claim that the percentage of commercial truck drivers who suffer from sleep apnea is not 7.5 % ? Use a 0.01 level of significance. Step 2 of 3: Compute the value of the test statistic. Round your answer to two decimal places. Answer 2 Points 24 Hawkes Learning Keypad Keyboard Shortcuts
