Question
In the fictional city of Statisticsville, last year residents spent an average of $12 per month using grocery pickup services (where you purchase groceries online and then drive to the store to pick
them up). A journalist wants to know if people today in the (fictional) city of Statisticsville are spending more per month on average compared to last year. Her hypotheses are:
Hoi u =12
HA: H> 12
She selects a random sample of 89 people at a large public space in Statisticsville and finds their average spending per month on grocery pickup fees is $12.19 with a standard deviation of $4.15. All
necessary assumptions and conditions have already been checked and were met.
