    A rental agent claims that the mean monthly rent, , for apartments on the east side of town is less than $675 . A random sample of 18 monthly rents for apartments on the east side has a mean of $661, with a standard deviation of $24 . If we assume that the monthly rents for apartments on the east side are normally distributed, is there enough evidence to conclude, at the .05 level of significance, that is less than $675 ?
