John plans to practice piano at least 2 1 2 212 hours this weekend. If he practices 1 1 6 116 hours on Saturday and 1 1 4 114 hours on Sunday, will he meet his goal? A. Yes; he will practice a total of 2 5/12 hours, and 2 5/12 > 2 1/2.

B. No; he will practice a total of 2 5/12 hours, and 2 7/12 < 2 1/2

C. Yes; he will practice a total of 2 7/12 hours, and 2 7/12 < 2 1/2

D. No; he will practice a total of 2 7/12 hours, and 2 7/12 < 2 1/2

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.
