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 15 million out of the 312.7 million Americans suffer from sleep apnea, or approximately 4.8%. 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 4.8%, a simple random sample of 339 commercial truck drivers is examined by a medical expert, who concludes that 7 suffer from sleep apnea. Does this evidence support the claim that the percentage of commercial truck drivers who suffer from sleep apnea is not 4.8%? Use a 0.05 level of significance. Step 3 of 3 : Draw a conclusion and interpret the decision. Answer Tables Keypad Keyboard Shortcuts We reject the null hypothesis and conclude that there is insufficient evidence at a 0.05 level of significance that the percentage of commercial truck drivers who suffer from sleep apnea is not 4.8%. We fail to reject the null hypothesis and conclude that there is sufficient evidence at a 0.05 level of significance that the percentage of commercial truck drivers who suffer from sleep apnea is not 4.8%. We fail to reject the null hypothesis and conclude that there is insufficient evidence at a 0.05 level of significance that the percentage of commercial truck drivers who suffer from sleep apnea is not 4.8%.
