Question

Please read the following prompt, analyze the following graph, and complete question 6.a

A concern in allowing the tinting of car front side windows is that tasks performed through these windows often require the rapid detection of low-
contrast, unillumitated targets. If the tinting interferes with detection of targets then road safety may be compromised.
A random sample of 182 US adults was selected to participate in a study. Participants were randomly assigned to drive a car with a predetermined
degree of tinting on the front side windows of the car (none: no window tinting, low: low window tinting, and high: high window tinting). For each
participant, the inspection time was recorded (inspection time is defined as the time required to perform a simple discrimination task through the
treated windows (in milliseconds)). Many variables were recorded for each participant, however we will focus our attention on the following variables:
1.
Tint (degree of window tinting: none= no window tinting, low= low window tinting, high= high window tinting)
2.
Inspect (inspection time (milliseconds)
The primary study question is to use these results to investigate the effect of the degree of window tinting on the inspection time, on average.
The boxplot shows the results of the study.
