Answer:
1. $5
2. $38.4
Step-by-step explanation:
1) $5
2) 120/100 x 32 = $38.4
Answer:
628
Step-by-step explanation:
We have the standard deviation of the sample, so we use the t-distribution to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 12 - 1 = 11
95% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 11 degrees of freedom(y-axis) and a confidence level of 
. So we have T = 2.2
The margin of error is:
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 665 - 37 = 628 hours.
The answer is 628
Hey there!
The correct answer is 
~ Write the equation
~ Simplify
~ Subtract 
from both sides
~ Subtract 
from both sides
~ Divide both sides by 8
Hope it helps and have a great day!
