A recent study has shown that 68% of parents allow their children to ride their bicycles without using a helmet. If we randomly select 25 parents, what is the probability that exactly 18 of the parents allow their children to ride their bicycles without using a helmet? Compute your solution as a decimal and round your final answer to four decimal places. P(exactly 18) = __________
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. 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.
