A four-day charity fundraiser received 53 donations on the first day, 49 donations on the second day, 43 donations on the third day, and 63 donations on the final day. What was the mean number of donations per day?

mean = 52

Step-by-step explanation:

Just add all four together and divide by 4. That's the mean.

Sum (49 + 43 + 53 + 63)/4 = 208

Mean = 208 /4 = 52

step-by-step explanation:

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.
