The random variable x represents the number of girls among 10 children. Use the range rule of thumb to determine whether 1 girl in 10 births is a significantly low number of girls. Click the icon to view the table Use the range rule of thumb to identify a range of values that are not significant The maximum value in this range is girls (Round to one decimal place as needed.) The minimum value in this range is girls (Round to one decimal place as needed) Based on the result, is 1 girl in 10 births a significantly low number of girls? Explain 0 A.

Explanation / Answer

here mean value =np =10*0.5 =5

and std deviation =(np(1-p))1/2 =(10*0.5*(1-0.5))1/2 =1.58

hence maximum value =mean +2*std deviation =8.2

minimum value =mean -2*std deviation =1.8

option B is correct
