Acura cars have higher mpg while BMW has more variation in mpg.
From the histograms of mpg distribution for the two makes of car :
- ACURA has most of its values at the center of the distribution with it's tail more conspicuous to the right at a maximum mpg value of 40 and a minimum of about 17.5 to the left.
- BMW on the other hand has its mpg distribution more spread out towards both sides of the distribution, ranging from a minimum of about 3 mpg and to a maximum of about 37.5 mpg.
- Hence, we could infer that, the histogram plot of BMW is more dispersed and hence has greater variation than ACURA.
- Since ACURA has it's peak at the middle, with minimum and maximum mpg values of 17.5 and 40 respectively, which are sufficiently greater than the minimum and maximum mpg values of BMW (3.0 and 37.5 respectively). Then we can conclude that ACURA has greater mpg.

Considering the p-value of 0.6, the decision is that we do not reject the null hypothesis.
<h3>What are the hypothesis tested?</h3>At the null hypothesis, we test if the proportions are equal, that is:
At the alternative hypothesis, we test if they are different, that is:
- If the p-value is greater than the significance level, we do not reject the null hypothesis.
- If the p-value is less than the significance level, we reject the null hypothesis.
In this problem, the significance level is of 0.1, while the p-value is of 0.6, hence the correct decision for the test is to not reject the null hypothesis.
