Solution
Null Hypotheses:
H0 mu1 = mu2
Ha: mu1 not equal to mu2
(Two tailed test for comparison of means)
n1 = n2 = 50
t = 1.8288
df = 98
standard error of difference = 2.657
p value =0.0705
Because p value > alpha 0.05 accept null hypothesis
The means in city and suburbs do not have statistically significant differences.
There is not enough evidence
