Both work but if it is a decrease using the first one it will be -xx%
Hope this helps :)
Answer:
Step-by-step explanation:
The null and the alternative hypothesis can be computed as:
The t- student test statistics can be computed as:
t = -2.017
degree of freedom = (n₁-1)+(n₂-1)
= (100-1) + (130-1)
= 228
At t = -2.017 and 228 df
P-value = -0.224
Decision rule: Not to reject the null hypothesis if the p-value is greater than ∝(0.01)
Conclusion: We reject the null hypothesis since the p-value is less than ∝.
Thus, there is sufficient evidence to conclude that the mean age of entering prostitution in Canada is lower than that of the United states.
