Question

On the high attempts the picture was cut off and the last one is 98 in the picture​

Answer 1

Below in bold.

Explanation:

Mean = (98+92+90+78+83+88+95)/7

= 89.1 to nearest tenth.

Deviations:

98 - 89.1 = 8.9

92 - 89.1 = 2.9

90 - 89.1 = 0.9

78 - 89.1 = -11.1 = 11.1 (absolute value)

83 - 89.1 = 6.1

88-89.1 = 1.1

95 - 89.1 = 5.9

So the MAD

= (8.9+2.9+0.9+11.1+6.1+1.1+5.9)/7

= 36.9/7

= 5.27

= 5.3 to nearest tenth.
