Answer:
1) A
2) C
Step-by-step explanation:
The range is all real y values, in this case it includes zero and continues going downward towards negative infinity.
The domain is all real x values. In this case it includes zero and continues increasing to positive infinity.
Hope this helps!
If you divide a negative by a negative, your result will be positive.
For example, -5/-1=5.
Given:
Population proportion,
= 57% = 0.57
Population standard deviation, σ = 3.5% = 0.035
Sample size, n = 40
Confidence level = 95%
The standard error is
The confidence interval is
where
= sample proportion
z* = 1.96 at the 95% confidence lvvel
The sample proportion lies in the interval
(0.57-1.96*0.0783, 0.57+1.96*0.0783) = (0.4165, 0.7235)
Answer: Between 0.417 and 72.4), or between (41% and 72%)
