Assignment Help Basic Statistics
##### Reference no: EM1318342

Prior to expanding the facilities of a town library, it was determined that 385 books per day were loaned out. It was believed that a new addition to the building would increase the mean number of books loaned out per day. After completion of the new addition, a random sample of 35 days showed a mean of 395 and a standard deviation of 26 books loaned out per day. At the 10% level of significance, is there sufficient evidence to indicate that more books are being loaned out per day, on the average?
