Mr Andrew is the owner of a small bakery in a large town. He believes that the smell of fresh baking will encourage customers to purchase goods from his bakery. To investigate this belief, he records the daily sales for 10 days when all the bakery's windows are open, and the daily sales for another 10 days when all the windows are closed. The following sales, in $, are recorded: 215.5 204.1 177.6 一 202.0 204.5 208.8 192.2 Window 207.0 190.8 215.6 193.5 187.8 185.7 оpen Windows 199.4 205.4 closed 200.6 181.8 169.2 172.2 192.8 Assuming that these data may be deemed to be random samples from normal populations with the same variance, investigate at the 0.05 level of significance the baker's belief.
