Answer:
The margin of error for her confdence interval is of 0.3757.
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used 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 = 18 - 1 = 17
99% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 17 degrees of freedom(y-axis) and a confidence level of . So we have T = 2.8982
The margin of error is:
In which s is the standard deviation of the sample and n is the size of the sample.
Standard deviation of 0.55 meters.
This means that
What is the margin of error for her 99% confidence interval?
The margin of error for her confdence interval is of 0.3757.
Answer:
The correct option is commutative property.
Step-by-step explanation:
The expression that Renee is simplifying is:
It is provided that, Renee recognizes that 7 and are reciprocals, so she would like to find their product before she multiplies by
.
The associative property of multiplication states that:
The commutative property of multiplication states that:
The distributive property of multiplication states that:
The identity property of multiplication states that:
So, Renee should use the commutative property of multiplication to find the product of 7 and ,
Thus, the correct option is commutative property.
