The accompanying 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. Use the range rule of thumb to determine whether 1 girl in 10 births is a significantly low number of girls. Use the range rule of thumb to identify a range of values that are not significant. a. The maximum value in this range is ​(Round to one decimal place as​ needed.)   b. The minimum value in this range is ​(Round to one decimal place as​ needed.)
