Ahypothesis will be used to test that a population mean equals 7 against the alternative that the population mean does not equal 7 with unknown variance. what are the critical values for the test statistic t0 for the following significance levels and sample sizes?

(a) ? = 0.01 and n = 20 (b) ? = 0.05 and n = 12 (c) ? = 0.10 and n = 15

View solution attached below.

Hope this helps. Thanks

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.

step-by-step explanation: just trying to get points sorry : (

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
