A silicon-valley marketing guru employed by Apple Inc. takes a hit of LSD and hypothesizes that if the iPhone XS were placed under a blue light it will induce an unsuspecting customer to purchase
it more often. Apple Inc., always trusting in the power of LSD to generate deeper insight into
selling stuff, decides to act on this immediately. So, it selects a random sample of 225 stores where
the iPhone XS are placed under said blue light. It also deploys an army of Steve Jobs fanboys to
collect data and calculate the average sales volume from stores with the new lighting. The data
is as follows: In stores with the lighting, the average sales volume is $328,754 with a standard
deviation of $227,000. The average sales volume per store, from previous data, was $300,000. Does
this new sales strategy impact the buying habit of the customer in any way? Set up a hypothesis
test of significance value 5% to test this.
