Question 1 (1 point) The Center for Disease Control and Prevention reported that 1 in 25 (4%) adult drivers (aged 18 or older) had fallen asleep while driving (drowsy driving). If we take a random sample of 300 drivers aged 18 years or older, what is the expected value and standard error of the proportion of adults who were drowsy driving? [Source: https://www.cdc.gov/sleep/about_sleep/drowsy_driving.html] O A) EV = 0.40; 0.0283 O B) EV = 0.04; SE = 0.0113 O C) EV = 12; SE = 3.3941 O D) EV = 4; SE = 0.2309 O E) EV = 25; SE = 1.9596Question 2 (1 point) According to the National Highway Traffic Safety Administration, the average age of drivers who were involved in a fatal crash is 39.4 years (with a standard deviation of 17.4 years). Suppose a random sample of 50 drivers involved in a fatal crash is selected. [Source: https://crashstats.nhtsa.dot.gov/Api/Public/ViewPublication/810853] What is the probability that the average age of drivers involved in fatal crash in the sample is above 35?
