Answer:
The correct option is (a+b)+c
Step-by-step explanation:
The correct option is (a+b)+c
According to the Associative property for Addition:
a+(b+c)=(a+b)+c
The associative property states that you can add or multiply regardless of how the numbers are grouped.
.If you are adding or multiplying it does not matter where you put parenthesis.
Thus the correct option is A....
Answer:
A. (4.78, 6.90)
Step-by-step explanation:
Using the following formulas the lower and upper limits of the Interval are calculated
Lower limit = mean - (standard deviation /√sample size)* Zr
Upper limit = mean + (standard deviation /√sample size)* Zr
Zr depends on confidence interval and can be found in a z table
Zr for 90% = 1.645
then
Lower limit = 5.84 - (4.98 /√60)* 1.645 = 4.78
Upper limit = 5.84 + (4.98 /√60)* 1.645 = 6.90
