Answer:so u asking how much was ate total?
Step-by-step explanation:
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 correct answer is: Commutative Property
Further Explanation:
The commutative property states that the order of number doesn't matter and changing the order of numbers or variables will produce the same result.
<u>Commutative Property of Addition:</u>
The Commutative Property of addition means that an expression can be written as a + b = b + a.
<u>Commutative Property of Multiplication:</u>
The Commutative Property of multiplication means that an expression can be written as a • b = b • a
Hence, the correct answer is: Commutative Property
