Question:
=+$75.00. The price was recently increased to $1.00 per can.
A random sample of n 5 20 days after the price increase yielded a sample average daily revenue and sample standard deviation of $70.00 and $4.20, respectively. Does this information suggest that the true average daily revenue has decreased from its value before the price increase? Test the appropriate hypotheses using a 5 .05.
