A furniture store claims that a specially ordered product will take

on average,   =  days (5 weeks) to arrive. The standard deviation of these waiting times is  days. We suspect that the special orders are taking longer than this. To test this suspicion, we track a random sample of  special orders and find that the orders took a mean of  days to arrive. Assume that the population is normally distributed. Can we conclude at the level of significance that the mean waiting time on special orders at this furniture store exceeds 35 days?
Perform a one-tailed test. Then fill in the table below.
Carry your intermediate computations to at least three decimal places, and round your responses as specified in the tabl
