I need help ASAP!! Mike is a local farmer who is interested in how often residents in her town go to a farmer's market each month. She surveys 124 families and finds that, on average, those families visit a farmers' market 4.2 times
per month with a sample standard deviation of 1.3. If Mika wants to be 99% confident (z = 2.58) using this
sample, what should her margin of error be and what does it mean?
