B) Need minimum value

The accompanying data table describes results from groups of 10 births from 10 different sets of parents. The random variable x represents the number of girls among 10 children. Complete the questions below EEE Click the icon to view the data table. Use the range rule of thumb to identify a range of values containing the usual numbers of girls in 10 births More Info The maximum usual value is Round to one decimal place as needed.) P(x 0.003 0.016 0.039 0.116 0.204 0.241 0.196 0.115 0.041 0.017 0.012

Explanation / Answer

Maximum usual value comes at mean+2SD or P(x>a)=0.025

Hence we can see that X where P(X>a)=0.025

P(X<=8)=1-0.017-0.012=0.971

But P(X<=9)=0.988

Hence for 0.975,we need to interpolate to get X=8.23=8.2
