A professor wants to show that students can improve their political science grades by reading the newspaper daily. He randomly assigns fifteen students to refrain from reading any newspapers before their first exam. He instructs the other fifteen students to read the newspaper in his office daily for one hour until the exam. He then wants to compare the exam grades of the two groups. Assume you analyzed the data. You found t = 1.10. Do you reject the null? (Yes OR No)

12*c

step-by-step explanation:

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
