Answer: 95% confidence interval would be (0.555,0.745).
Step-by-step explanation:
Since we have given that
n = 97
x = 63
So, we get that

At 95% confidence interval , z = 1.96
so, Margin of error would be

So, interval would be

Hence, 95% confidence interval would be (0.555,0.745).
Answer:
25
Step-by-step explanation:
A coefficient is a number multiplied by a variable and in this case the variable would be (1-4).
The number being multiplied by the variable is 25.
Answer: 50
Step-by-step explanation:
Answer:
m∠2 = 78°
Step-by-step explanation:
From the given picture,
lines 'm' and 'n' are the parallel lines and line 't' is the transverse line.
∠1 and angle with the measure of 78° are corresponding angles.
Therefore, m∠1 = 78°
m∠1 = m∠2 [Vertical angles are equal]
m∠2 = 78°
