The top ten scores on a quiz in two classes are listed below. class a: 100,100,100,90,95,85,92,98,92,88 class b: 100,100,98,95,95,96,95,92,81,88 which statement is true concerning the data? a)the mode is the same for both classes b)the range is the same for both classes c)the mean is the same for both classes d)the median is the same for both classes

The mean is the same for both classes

Step-by-step explanation:

Class A scores of 10 students: 100,100,100,90,95,85,92,98,92,88

Arrange the data in ascending order

85,88,90,92,92,95,98,100,100,100

Mode = 100 since it occurred more times.

Range = Maximum - Minimum = 100-85 = 15

Mean =

Mean =

Mean = 94

Median = mid value

n = 10 (even)

So, median =

                  =

                 =

                 =

                 =

Median = 93.5

Class B scores of 10 students : 100,100,98,95,95,96,95,92,81,88

Arrange the data in ascending order

81,88,92,95,95,95,96,98,100,100

Mode = 95 since it occurred more times.

Range = Maximum - Minimum = 100-81 = 19

Mean =

Mean =

Mean = 94

Median = mid value

n = 10 (even)

So, median =

                  =

                 =

                 =

                 =

Median = 95

So, The mean is the same for both classes is same i.e. 94.

Hence Option C is correct.

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
