The operation manager at a tire manufacturing company believes that the mean mileage of a tire is 48,56448,564 miles, with a standard deviation of 32933293 miles. What is the probability that the sample mean would differ from the population mean by less than 386386 miles in a sample of 281281 tires if the manager is correct

table 1

step-by-step explanation:

1-16

2-32

4-64

8-128

all multiples of 16

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.
