exis [7]3 years ago
5 0

Answer:

A and B

Step-by-step explanation:

The surface area is 2\pi rh+2\pi r^2

Researchers interviewed street prostitutes in Canada and the United States. The mean age of the 100 Canadian prostitutes upon en
levacccp [35]

Answer:

Step-by-step explanation:

The null and the alternative hypothesis is:

H_o: \mu_c \ge \mu_{us}

H_a : \mu_c < \mu_{us}

The t- student test statistics can be computed as:

t = \dfrac{x_c- x_{us}}{\sqrt{\dfrac{\sigma_c^2}{n_c} + \dfrac{\sigma_{us}^2}{n_{us}} }}

t = \dfrac{19- 21}{\sqrt{\dfrac{7^2}{100} + \dfrac{8^2}{130} }}

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.
