We' supposed to indicate which statement is true/false.
Note that, if a sample size is 40 or over, we can use the t distribution even with skewed data. So it's not highly sensitive to non-normality of the population from which samples are taken. So statement A is false.
It's true that the t-distribution assumes that the population from which samples are drawn is normally distributed. So B is true.
For skewed data or with extreme outliers, we can't use the t distribution. We only use t distribution as long as we believe that the population from which samples are drawn is closed to a bell-shape. So C is true.
Lastly, statement D is against statement C. So D is false.

Q3
To find the percent of motorcycles in traffic
divide the number of motorcycles by the total number of vehicles and then multiply by 100%
Q4
Mode means most often. In a histogram, it is the tallest column. It is the first column, which looks like 43 cars
The <em><u>correct answer</u></em> is:
Corresponding (for both blanks)
Explanation:
Corresponding angles are angles that are in the same relative position to both the parallel line they are on and the transversal. In this case, SQU and WRS are both above the parallel line they are on and on the same side of the transversal; this makes them corresponding angles. This also means it is the corresponding angles postulate.
