The point Estimate is 0.645 , the confidence interval is (0.525 ,0.764).
<h3>What is Point Estimate ?</h3>
The point estimate is the proportion of success in the sample.
From the data given
p = 40/62
p = 0.645
The point Estimate is 0.645
(b) Confidence interval for true proportion is

For 95 % Z = 1.96
p =0.645
1-p = 0.355
putting the values

(0.525 , 0.764)
Lower Limit = 0.525
Upper Limit = 0.764

Answer:
Well there aren't any options but a number line pointing right with the circle being empty (For example, ○) on the point -2.
Answer:
f(-3) = 16
Step-by-step explanation:
You substitute -3 to x.
f(-3) = 2(-3)² - 5(-3) - 17
f(-3) = 16.
As for the coordinates, the coordinates plotted in the graph above are (1,-1) and (2,-2).
