The table shows the ingredients used in a medicine. if all the decimals were rounded to the nearest whole percent, would this table be in comparing the amount of each ingredient? explain. ingredient percent substance a 19.6% substance b 19.9% substance c 19.5% substance d 14.5% a. yes; substance b would still be the largest part of the medicine. b. no; three of the percentages would round to 19%. c. no; three of the percentages would round to 20%. d. no; two of the percentages would round to 20%.

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.
