Questins A, B, and C Please!

 

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 37 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 α = 0.10.

---

**(a) What is the level of significance?**

State the null and alternate hypotheses.

- \( H_0: p = 0.77, H_1: p > 0.77 \)
- \( H_0: p < 0.77, H_1: p = 0.77 \)
- \( H_0: p = 0.77, H_1: p < 0.77 \) [Selected]
- \( H_0: p = 0.77, H_1: p \neq 0.77 \)

---

**(b) What sampling distribution will you use?**

- The Student's t, since np > 5 and nq > 5.
- The Student's t, since np < 5 and nq < 5.
- The standard normal, since np < 5 and nq < 5.
- The standard normal, since np > 5 and nq > 5. [Selected, incorrect]

What is the value of the sample test statistic? (Round your answer to two decimal places.)
