Transcribed Image Text:Es
On their website, a property management company states that the mean monthly rent for apartments on
the east side of town is $650. A researcher for a consumer advocacy group believes that, due to the
construction of newer apartment complexes in neighboring towns, the mean monthly rent on the east side.
u. is now lower. A random sample of 9 monthly rents for apartments on the east side has a mean of $647
with a standard deviation of $15.
Assume that current monthly rents for apartments on the east side are approximately normally distributed.
Based on the sample, is there enough evidence to conclude, at the 0.10 level of significance, that the
population mean monthly rent is now less than what is stated on the website?
Perform a one-tailed test. Then complete the parts below.
Carry your intermediate computations to three or more decimal places. (If necessary, consult a list of
formulas.)
(a) State the null hypothesis Ho and the alternative hypothesis H,.
: H:
0
: 'H
믐
(b) Determine the type of test statistic to use.
(a)
(Choose one) ▼
O=0
OSO
(c) Find the value of the test statistic. (Round to three or more decimal
places.)
(d) Find the critical value. (Round to three or more decimal places.)
(e) Can we conclude that the mean monthly rent for apartments on the east side is less
than what is stated on the website?
OYes
ONo
