The confidence interval for the mean population of drivers who do not like driving at night is 57.79% - 62.21%.
<h3><u>Confidence interval</u></h3>
To determine what is the 92% confidence interval for the population mean of drivers that do not like driving at night, the following calculation must be performed:
- 1500 = 100
- 900 =X
- 900 x 100 / 1500 = X
- 60 = X
- 60 x 0.92 = 55.2
- 60 x 1.08 = 64.8
Therefore, the confidence interval for the mean population of drivers who do not like driving at night is 57.79% - 62.21%.

I’m pretty sure the answer is 30
Answer:
The answer is 17 2/5
Step-by-step explanation:
To find this, first add all the fractions together.
1/5 + 2/5 + 4/5 = 1 2/5
Now add all the whole numbers together.
8 + 3 + 5 = 16
Now add the two together.
16 + 1 2/5 = 17 2/5
Answer: 2 quarters = 50 cents, 3 dimes = 30 cents, 4 nickels =20 cents. 50+30+20=100 cents.
Step-by-step explanation:
Answer:
y = - 5/6 x + 1
Step-by-step explanation:
y = mx + b m: slope b: y intercept
point (6 , -4) x = 6 y = -4
b = y - mx = -4 - ((-5/6) x 6) = - 4 + 5 = 1
equation: y = - 5/6 x + 1
