Acoffee shop surveyed three groups of 5 customers to find out how many cups of coffee the customers drink in one day. the table shows the results of the three samples. group 1 {1, 3, 2, 2, 4} group 2 {4, 1, 3, 2, 1} group 3 {5, 4, 6, 4, 6} identify any surveys that are likely biased. based on the unbiased surveys, estimate the mean number of cups of coffee the customers drink in one day. enter your answer in the box. round to the nearest whole number.

Based on the unbiased surveys, the mean number of cups of coffee the customers drink in one day is two.

Step-by-step explanation:

I took the quiz

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.

the answer is 375 miles
