Minimum required sample size for a desired margin of error and confidence level when it is a proportion problem: n = (z2÷margin of error2)*p-hat*q-hat
The maximum value of p-hat*q-hat occurs where p-hat = .5 (found by taking the derivative of (p-hat)*(1-p-hat) and setting it equal to 0 to find the maximum. n = ( 2.5762( for 99% confidence interval)÷.0482 )*.5*.5 = 720.028 or 721
To get the answer, you subtract the time she spent playing with her dog (5 minutes) from 15. 15-5=10. then you subtract the time she rode her bike (4 minutes). 10-4=6. since there are 6 minutes left, she spent 6 minutes catching bugs
