Question 29-31 are related to the following On a freeway 85% of vehicles violate the speed limin=0.85) From the population of all vehicles on the freeway, you clock repeated random samples of size 400 vehicle. 29 What fraction of sample proportions (p's) from samples of size 400 fall with 10.03 (3 percentage points) from the population proportion. a b C d 30 The middle interval that captures 95% of sample proportions is, a 0.825 0.815 0.801 0.781 b C 0.9343 0.9071 0.8807 0.8550 d 0.875 0.885 0.899 0.919 31 To build a middle interval around the population proportion such that 95% of all sample proportions deviate from the population proportion by no more than 10.02 (2 percentage points), what is the minimum sample size to vield this interval? 1225 1289 1357 1428 32 The middle interval around the population proportion which captures 95% of sample proportions of vehicles that exceed the speed limit is: 0792 0848
