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:
6. (a) 7. (b) Im pretty sure 8. (d)
Step-by-step explanation:
A real number is basically any number whatsoever, meaning a real number can also be irratonal.
7. pi is 3.1415926535... but doesn't repeat so it doesn't go on a number line, the sq root of -16 is -4 which has a place on the line, and the repeating decimal would have no place on a number line.
8. irrational means it repeats without a pattern, such as pi (3.1415926535...) which is why the answer is d
Answer:
x: {-3, 5}
Step-by-step explanation:
Step 1. Find least common denominator
Step 2. Multiply missing factors on top AND bottom
Step 3. Combine like terms
Step 4. Simplify (get rid of denominator)
Step 5. Solve for x
LCD = 
OR 
<u>x = -3, 5</u>
