A random sample of 10 onebedroom apartments from your local newspaper has these monthly rents (dollars):
500 650 600 505 450 550 515 495 650 395
Do these data give good reason to believe that the mean rent of all advertised apartments is greater than $500 per month? Carry out a complete significance test.

Best ResponseYou've already chosen the best response.0you have to use a correction factor we cannot assume this sample standard deviation is the same as the real standard deviation of the population

Best ResponseYou've already chosen the best response.0can you help me find the t value? this is what I did but it is not right. (531  500) / the standard deviation (82.79157) = 0.374
