The formula for the confidence interval is given by
Sample mean + z*[σ/√n], and
Sample mean - z*[σ/√n]
We have:
Sample mean = 23.95
n = 40
σ = 2.55
z* for 99% confidence = 2.58
Substitute these values into the formula, we have
23.95 + (2.58)(2.55÷√40) = 24.99
23.95 - (2.58)(2.55÷√40) = 22.91
So the lower interval is 22.91 and the highest interval is 24.99
Answer:
Final answer is choice B. 
Step-by-step explanation:
We need to factor the given expression 
Hence final answer is choice B.
<em>46 - 40 = 6</em>
Carmen will be paid 6 hours at overtime hourly rate.
