Multiply both sides by 72x
8x+%2B+9x+=+72
17x+=+72
x+=+4.24 hrs
.24%2A60+=+14.4

Answer:
Step-by-step explanation:
The null and the alternative hypothesis is:

The t- student test statistics can be computed as:


t = -2.017
degree of freedom = (n₁ - 1) + (n₂ - 1)
= (100 - 1) + (130 - 1)
= 228
Using the data of t-value and degree of freedom;
The P-value = -0.224
Decision rule: Do not 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 ∝.
Therefore, there is enough evidence to conclude that the mean age of entering prostitution in Canada is lower than that of the United States.
