2.54-1.66
0.88
the answer is 0.88
The answer is C- 99.5ft :)
its A because 55 - 17 = 38
17 * 2 = 34
38 - 34 = 4
hope this helps :)

The standard deviation of a binomial variable is
sqrt(n*P*(1-P))
where n is the sample size and P is the probability of one of the outcomes.
The sample size is 55 and we'll assume that both male and female are equally likely outcomes.
standard deviation = sqrt(55*.5*.5) = 3.7081%
44% is 1.6181 standard deviations away from the mean of 50%.
Looking this up on a standard deviation chart gives .0526 probability which we'll round to 0.053</span>
