A scientist is interested in the percentage of volcanoes (that have erupted at least once in recorded history) that have erupted at least 15 times . The scientist was only able to obtain data on a random sample of 179 volcanoes and, thus, will make an estimate based on this sample data. To help the scientist, create and interpret 90% and 98% confidence intervals to estimate the desired quantity. Include sample mean, sample standard deviation, and margin of error/upper limit/lower limit for each.
