Kennedy has a bag that contains strawberry chews, apple chews, and lime chews. She performs an experiment. Kennedy randomly removes a chew from the bag, records the result, and returns the chew to the bag. Kennedy performs the experiment 38 times. The results are shown below: A strawberry chew was selected 18 times. A apple chew was selected 11 times. A lime chew was selected 9 times. Based on these results, express the probability that the next chew Kennedy removes from the bag will be a flavor other than apple as a decimal to the nearest hundredth

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.
