Answer:

[tex] \% Change = \frac{9}{64} *100 = 14.0625\% \approx 14\%[/tex]

So then we have approximately 14% of the values higher than 95.5

Step-by-step explanation:

For this case we assume that the info is given on the figure attached.

From this figure we have the following frequencies for each class

Class                  Frequency

___________________________

70.5-75.5                13

75.5-80.5                7

80.5-85.5                6

85.5-90.5                10

90.5-95.5                19

95.5-100.5               9

____________________________

Total                        64

So we have a total of 64 values and we want to find the percentage of students that scored higher than 95.5 so we can use the formula of relative change and we got:

[tex] \% Change = \frac{9}{64} *100 = 14.0625\% \approx 14\%[/tex]

So then we have approximately 14% of the values higher than 95.5
