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
The answer is 8 by itself i think
No they did not eat the whole thing. They are 6 out of 8 pieces of the orange. Therefore there is still 2 pieces left
Answer:
it is good and people need to do math problems
Step-by-step explanation:
If it's just a vertical line, then it could be displayed as: x = 5.
A vertical line is not actually a function, and because of such, the entire line is just the value of the x value, as it will never have enough x value.
