Relationship between the number of hours and the number of miles Sam has driven is proportional.
x = 1 number of hours
y = 30 number of miles
This means that for every hour Sam travels, he travels an additional distance of 30 miles.
Based on the calculations, the correct value of the test statistic is equal to 3.2.
<h3>How to calculate value of the test statistic?</h3>
For samples A and B, the hypothesis is given by:
H₀: μ₁ ≤ μ₂
H₁: μ₁ > μ₂
Since both samples have a normal distribution, we would use a pooled z-test to determine the value of the test statistic:
Substituting the given parameters into the formula, we have;
z = 3.2.
