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. x P(x)0 0.0041 0.0132 0.0363 0.1154 0.2065 0.2386 0.2017 0.1168 0.0459 0.01310 0.013 The maximum value in this range is __ girls. (round to one decimal places 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. A. No, 1 girl is not a significantly low number of girls, because 1 girl is within the range of values that are not significant. B. Yes, 1 girl is a significantly low number of girls, because 1 girl is below the range of values that are not significant. C. Yes, 1 girl is a significantly low number of girls, because 1 girl is above the…
