The U.S. Department of Transportation, National Highway Traffic Safety Administration, reported that 77% of all fatally injured automobile drivers were intoxicated. A random sample of 54 records of automobile driver fatalities in a certain county showed that 34 involved an intoxicated driver. Do these data indicate that the population proportion of driver fatalities related to alcohol is less than 77% in Kit Carson County? Use a - 0.10. (a) What is the level of significance? State the null and alternate hypotheses. O Ho: p = 0.77; H: p < 0.77 O Họi p < 0.77; H: p = 0.77 O Họ: p = 0.77; H: p * 0.77 O Họ: p- 0.77; H,: p > 0.77 (b) What sampling distribution wll you use? O The standard normal, since np > 5 and ng > 5. O The standard normal, since np < 5 and ng < 5. O The Student's t, since np < 5 and ng < 5. O The Student's t, since np > 5 and ng > 5.
