Answer:
Its statistically significant, that Mean monthly apartment rent in town east < $ 750
Step-by-step explanation:
Null Hypothesis [H0] : Mean monthly apartment rent in town east = 750
Alternate Hypothesis [H1]: Mean monthly apartment rent in town east < 750
t = (x' - u) / (s / √n)
x' = sample mean = 737
u = population assumed mean = 750
s = standard deviation = 23
n = no. of units in sample
t = (737 - 750) / (23 / √18) = -13 / 5.4212
= -2.39
t tabulated critical value : for one sided 0.05 significance level, at 17 degrees of freedom = -1.740
t calculated value, -2.39 < t tabulated critical value, - 1.740
We reject the null hypothesis, & state that its statistically significant, that Mean monthly apartment rent in town east < 750
