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.
Answer:
below
Step-by-step explanation:
Two students are selling cookies at a bake fair. Jake is selling cookies for $2.50 each plus $6 for the packaging. Kevin is selling cookies for $3.25 each plus $3 for the packaging. How ma cookies would both have to sell to make the same amount of money?
2.5x + 6 = 3.25x + 3
2.5x = 3.25x - 3
-0.75x = -3
x = 4 cookies
Best of Luck!
The answer is letter D.

Answer: In about 8 years, she will reach the rate of $15.50
This is an exponential equation. We could write and solve the equation below to find the answer.
9.75(1.06)^x = 15.5
(1.06)^x = 15.5/9.75 Divide both sides by 9.75
x (log(1.06)) = log(15.5/9.75) Take the log of both sides and bring down the x.
x = log(15.5/9.75) / log(1.06) Divide both sides by log(1.06)
x = 7.956
Therefore, we can round it up to 8 years.
