Part One: Crime Analysis From 2016-17
Step 1:
H0 : μTotal perent change ≥ 0
Ha : μTotal perent change <0
Left tailed hypothesis test
Step 2:
Step 3
99% confidence interval for percent change
Analysis of Results
As the p value for the test is lower than the significance level and thus, null hypothesis will
be rejected and alternative hypothesis will be accepted. Hence, the conclusion can be drawn
that the crime level has decreased over the time. The hypothesised value of 0 is included in
the confidence interval. Hence,, the confidence interval result is in agreement with the
hypothesis test result.
Part Two: Gender Perception in the Workforce
Step 1:
H0 : p ≤ 0.1
Ha : p >0.1
Right tailed hypothesis test
Step 2:
