Answer:The margin of error is 0.01323 and 95% confidence interval is (0.674,0.73).
Step-by-step explanation:
Since we have given that
p = 0.70
n = 1200
We need to find the margin of error;
Margin of error would be
At 95% confidence level, α = 1.96
so, 95% confidence interval would be
Hence, the margin of error is 0.01323 and 95% confidence interval is (0.674,0.73).
Answer:
E. 0.759
Step-by-step explanation:
You can take this right triangle to have a base length side LM , height of LN and a hypotenuse of MN
The sine of angle ∠LMN is 0.759, find the value of ∠LMN
∠LMN=49.38°
Find angle ∠LNM
You know sum of angles in a triangle add up to 180°, given that this is a right-triangle, the base angle is 90° hence
∠LNM=180°-(90°+49.38°)
∠LNM= 180°-139.38°=40.62°
Find cos 40.62°
Cos 40.62°=0.7590
