Weekly sales of regular ground coffee at a supermarket have in the recent past varied according to a Normal distribution with a mean u=354 unites per week and standard deviation 33 units. The store reduces the price by 5%. Sales in the next three weeks are 405,378 and 411 units. Is this good evidence that average sales are not higher? The hypotheses are Ho= u=354 and Ha= u=354. Find the value of x bar. Also find P-value.
