Open Wages-HW9 data. Test if people with 16 years of EDUCATION and people with 12 years of EDUCATION have wages that are significantly different on average. Answer questions 5 to 8.5. What test did you perform? (6.25 points)a. Simple Regressionb. Multiple Regressionc. Two sided t-testd. None of these

Correct option: (c). Two sided t-test.

Step-by-step explanation:

A test is to be performed to determine whether the people with 16 years of education and 12 years of education have wages that are significantly different on average.

A sample is provided for the wages of people in both the category.

Compute the sample mean and sample standard deviations for both the sample using the formulas:

The hypothesis is:

H₀: The wages of the two groups is not different, i.e. μ₁ = μ₂.

Hₐ: The wages of the two groups is not different, i.e. μ₁ ≠ μ₂.

A test for the difference between two means is to be performed.

Since there is no information about the population standard deviations, use a t-test for the difference between two means.

Thus, the correct option is (c). Two sided t-test.

the distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.

if you could provide answer choices that might allow me to answer the question easier if my above answer isn't an option! (:
