A large furniture store has begun a new ad campaign on local television. Before the campaign, the long term average daily sales were $24,819. A random sample of 40 days during the new ad campaign gave a sample mean daily sale average of x = $25,910. Does this indicate that the population means daily sales are now more than $24,819? Determine by setting up a hypothesis test and interpreting your results in the context of this problem. Use a 1% level of significance. Assume s = $1917.
