I really need help with this question. If someone could help me it would be great.
A water ride has the minimum height requirement of 5 feet. The average height of children who visit the park is 4 feet 10 inches, with a standard deviation of 2 inches.
1.) What percentage of the children who go to the park qualify to ride?
Alright so by the $68-95-99.7$ rule, we have $32\%$ of people are either shorter than $4'6$ or taller than $5'0$
By symmetry of the bell curve, $\boxed{16\%}$ of kids fall under the taller than $5$ feet category and are eligible for the roller coaster. To be more precise, we can use $68.27-95.45-99.73$ to get $\boxed{15.865\%}$
