Please help me answer question b and c for this problem.A student project involved collecting data to see if there was a difference in the amount of time one had to wait at the drive-thru between two fast food restaurants, A and B. She randomly selected 30 cars at fast food restaurant A and 30 cars at fast food restaurant B. For each car chosen, she recorded how much time passed from the placement of the order to receiving their food at the pick-up window. The data is given in the table below measured in Seconds.

Please help me with the following statistics problem
A long-distance runner wants to compare the durability of two running shoe brands: Brand A and Brand B. Instead of testing them separately, 15 runners simultaneously wear Brand A on the left
foot and Brand B on the right foot during training runs.
The runner continues training as usual and tracks how many kilometers each shoe lasts before showing significant wear (e.g., loss of cushioning, outsole damage). Since both shoes experience the
same runner, terrain, and conditions, any lifespan difference can be attributed to the shoe brand rather than external factors.
Test whether Brand A running shoes have a significantly shorter lifespan than Brand B when worn under the same conditions by the same runner.

An article appeared in the Journal of Gambling Issues, in which the authors looked at random samples of Ontario residents who (i) have not completed some form of post-secondary education and
(ii) have completed some form of post-secondary education.
A code of 0 indicates the person does not have a gambling problem, a code of 1 indicates the person does have a gambling problem.
The data is found in the accompanying data file.

To count the frequencies of 0 and 1 in each sample, use the table(your_dataset_name$ column's name) function. Make sure to replace "your_dataset_name" with the actual name of your data file
and specify the correct column name.
For example: table(file60c5d1286c735$ CompletedPSEducation)
Let PNOPS represent the proportion of persons not completing some form of post-secondary education who have a gambling problem, and
PPs be the proportion of persons having completed post-secondary education who have a gambling problem.
