Also determine the necessary sample size if you wish to be 99% confident and can tolerate an error of 1 minute.

Part 3 - With a sample size not exceeding 150 but everything else staying the same, what confidence level can be achieved?

95

96

97

98

still 99

This was answered in a previous post. For part 3, you can probably still use the same confidence interval.
