Group of answer choices

Minimum: 850.85; maximum: 877.15

Minimum: 845.41; maximum: 882.59

Minimum: 837.71; maximum: 890.29

Minimum: 890.29; maximum: 837.71

Answer 1

GIven,

From the parameters we say it is a binomial distribution.Having parameters

Then,

Then,

The minimum value is  

Maximum value is  

Hence,the minimun value is 837.71 and maximum value is 890.29.

Hence, Option C) Minimum:837.71;Maximum:890.29 is correct answer.
