A random sample of 1100 vehicles on a freeway are clocked to test the hypothesis that the proportion of vehicles driving above 80 miles per hour is 25%. The number of vehicles in the sample driving above 80 mph is 308.
31 What is the sample proportion?
a 0.258 b 0.264 c 0.273 d 0.280
32 The test statistic is, a 2.38 b 2.30 c 2.21 d 2.14
33 The p-value is,
a 0.0011 Reject H? at α = 0.01.
b 0.0056 Reject H? at α = 0.01.
c 0.0107 Reject H? at α = 0.05.
d 0.0214 Reject H? at α = 0.05.
