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
D is the correct answer to this question.
