Question

1. The town where Lily lives has two main road intersections. Lily, a transportation engineer, suspects that one intersection is busier than the other. She sent two of her employees to track the number of cars that pass through each intersection at 5 different times of the day. Here are the number of cars passing through each intersection at each point in time:

Time
6am
9am
12pm
4pm
7pm
Intersection A
28
34
24
33
27
Intersection B
26
32
21
34
26
Lily wants to test if these results suggest intersection A is busier than intersection B. Assume that the necessary conditions for inference were met. Write the appropriate hypotheses.
What kind of test is this (i.e. paired or independent)
