Answer:

Range:- 6, 11, 15, 19, 30, 37, 45, 49, 50, 76, 79, 85, 85, 95

Range:- 96 - 6

= 90

Therefore, the answer is 90.

Mean:- 6 + 11 + 15 + 19 + 30 + 37 + 45 + 49 + 50 + 76 + 79 + 85 + 85 + 95

Mean:- 682/14

Mean:- 48.7142857

Therefore, the answer is 48.7142857.

Median:- 6, 11, 15, 19, 30, 37,) 45, 49,(50, 76, 79, 85, 85, 95

Median:- 45 + 49

= 94

Median:- 94/2

= 47

Therefore, the answer is 47.

Mode:- 6, 11, 15, 19, 30, 37, 45, 49, 50, 76, 79, 85, 85, 95

Mode:- 85

Therefore, the answer is 85.

Range = 90

Mean = 48.7142857

Median = 47

Mode = 85
