That's what I came up with. Still not sure of my answer.
Answer
given,
average rent of one bed room = $1229
sample size = n = 15
Sample mean rent = $1350
Assuming standard deviation equal to $250
the test hypothesis is
H o: µ=1229
H a: µ not equal to 1229
now we know,
![t = \dfrac{\bar{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}](https://tex.z-dn.net/?f=t%20%3D%20%5Cdfrac%7B%5Cbar%7Bx%7D-%5Cmu%7D%7B%5Cdfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%7D)
![t = \dfrac{\$ 1350-\$ 1229}{\dfrac{250}{\sqrt{15}}}](https://tex.z-dn.net/?f=t%20%3D%20%5Cdfrac%7B%5C%24%201350-%5C%24%201229%7D%7B%5Cdfrac%7B250%7D%7B%5Csqrt%7B15%7D%7D%7D)
t = 1.875
from t- table
a=0.05, the critical value is |t(0.025, d f= n-1 = 14)|=2.14
since t= 1.875 which is less than 2.14 we do not reject H o.
So we can not conclude that the monthly rent outside San Francisco differs from that in the city
