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
Mean 49.26 44.4 SD 14.95 11.38 SEM 2.11 1.61 N 50 50
