Answer:
$1226.78<x<$1301.22
Step-by-step explanation:
The formula for calculating confidence interval is expressed as;
CI = xbar ± z×(s/√n)
Given
Mean (xbar) = $1264
z is the z score at 90% CI = 1.645
s is the standard deviation = $150
n is the sample size = 44
Substitute
CI = 1264±1.645(150/√44)
CI = 1264±1.645(150/6.63)
CI = 1264±1.645(22.624)
CI = 1264±37.22
CI = (1264-37.22, 1264+37.22)
CI = (1226.78, 1301.22)
Hence the confidence interval of the mean is $1226.78<x<$1301.22
Hi there!
To solve this problem, we need to find the total amount of paint used by adding the two fractions.
First, we need to find the common denominators below adding.
1/2 = 2/4
1/4 = 1/4
The common denominator is 4.
Now, we add the mixed numbers together:
3 2/4 + 2 1/4 = 5 3/4
Since 5 3/4 can't be simplified, the answer is:
5 3/4 liters of paint
Hope this helps!
