c)
<em>Null hypothesis: H₀: </em>
<em>Alternative Hypothesis H₁</em>:
We will use two samples Z - hypothesis test
The test statistic
Z = -1.7043
|Z| = |-1.7043|
The tabulated value Z₀.₉₅ = 1.96
The calculated Z= 1.7043 < 1.96 at 0.05 level of significance
The null hypothesis is accepted
<u><em>Conclusion:-</em></u>
The evidence suggest not a higher proportion of females are annoyed by this behavior
