Answer:
62 is the minimum sample size needed
Step-by-step explanation:
We know that the population is approximately normally distributed so we will use a z-score for 95% confidence, which is 1.96. We are given the population standard deviation of σ = 20, and are given that the error should be 5 or less hours. The fact that it gives us sample data is irrelevant since we are told the population is approximately normally distributed and are given the population standard deviation.
See the attached photo for the calculation of the minimum sample size
