<h3>f(x) = -3·2^(x-1) -1</h3>
- reflection across the x-axis (multiplication by -1)
- vertical expansion by a factor of 3 (multiplication by 3)
- shift to the right 1 unit (replace x with x-1)
- shift down 1 unit (add -1 to the function value)
_____
<h3>f(x) = -1/4·2^(x+1) -1</h3>You may notice this is the same as the previous question, but with the vertical expansion factor 1/4 instead of 3, and the horizontal shift left instead of right.
- reflection across the x-axis (multiplication by -1)
- vertical compression by a factor of 4 (multiplication by 1/4)
- shift to the left 1 unit (replace x with x+1)
- shift down 1 unit (add -1 to the function value)
Answer:
1 is the answer
Step-by-step explanation:
Given that the U.S. Bureau of Labor Statistics reports that 11.3% of U.S. workers belong to unions.
(Right tailed test for testing of a sample proportion with population proportion)
Suppose a sample of 400 U.S. workers is collected in 2014 to determine whether union efforts to organize have increased union membership at 0.025 level of significance.
Test statistic Z = 1.31
p value for this right tailed test would be 0.095
This p value is greater than 0.025
Hence at 2.5% significance level the conclusion is correct
1 is the answer.
