Answer:
Step-by-step explanation:
Using either the critical value rule or the p-value rule, a conclusion can be drawn at a level of significance (alpha)
The null hypothesis: u = hypothesized mean
Alternative hypothesis: u > u0 or u < u0 for a one tailed test
Alternative hypothesis for a two tailed test: u =/ u0
To draw a conclusion by failing to reject the null hypothesis as stated then: using critical value
Observed z score > critical z score for both the one and two tailed test.
Or using p value:
P-value > alpha for a one tailed test
P-value > alpha/2 for a two tailed test
Thus, if a one-sided null hypothesis for a single mean cannot be rejected at a given significance level, then the corresponding two-sided null hypothesis will also not be rejected at the same significance level.
Answer: Subtraction property of equality.
Step-by-step explanation:
n + 9 = -3
You are trying to move 9 from one side to the other. To do that, you have to do the <em>inverse operation</em> and <u>subtract</u> nine from both sides. Your result would be n = -12.

Answer:
$60.80
Step-by-step explanation
20% Of $76=
Find how much a 20% discount is.
0.2 x 76 = 15.2
Then subtract the amount from the original price.
76 - 15.2 = 60.80
