A community is considering raising funds to pay for improvements to the community swimming pool. To measure the level of interest, community leaders survey patrons of the community pool on a Saturday afternoon. Of the 103
patrons surveyed, 87 approve of raising funds to pay for improvements. Which of the following is a true statement
regarding the design and results of the survey?
This is a convenience sample and is representative of community support
This is a convenience sample and likely overestimates support for raising funds.
This is a voluntary response sample and likely overestimates support for raising funds.
This is a voluntary response sample and likely underestimates support for raising funds

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.

b) well because you get well
