Give a correct interpretation of a 99% confidence level of 0.328 < μ < 0.486. a. 99% of sample means fall between 0.328 and 0.486. b. there is a 99% chance that the true value of μ will fall between 0.328 and 0.486. c. we are confident that 99% of values between 0.328 and 0.486 represent the true value of the population mean μ. d. we are 99% confident that the interval from 0.328 to 0.486 actually does contain the true value of the population mean μ.

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

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
