How much would a consumer pay for a T-shirt with a list price of $19 if the purchase was made in a province with a PST rate of 8%? Assume that the PST is applied as a percent of the retail price. Also assume that a GST of 5% applies to this purchase.

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

understand that i don't know the answers

will someone answer his question
