Answer:
A sample of 18 is required.
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Z-table as such z has a p-value of
.
That is z with a pvalue of
, so Z = 1.88.
Now, find the margin of error M as such
In which
is the standard deviation of the population and n is the size of the sample.
A previous study indicated that the standard deviation was 2.2 days.
This means that 
How large a sample must be selected if the company wants to be 92% confident that the true mean differs from the sample mean by no more than 1 day?
This is n for which M = 1. So



Rounding up:
A sample of 18 is required.
Answer:
When you multiply a negative number by a positive number then the product is always negative. When you multiply two negative numbers or two positive numbers then the product is always positive. 3 times 4 equals 12. Since there is one positive and one negative number, the product is negative 12.
Step-by-step explanation:
Answer: The monthly payments for a $5,000 loan would $146.51.
Step-by-step explanation: How it looks in the TVM Solver formula:
N = 36 ( 3 (years) x 12 (monthly payments) )
I% = 3.5%
PV = $5,000
PMT = 146.51 (or 146.08 if you choose BEGIN)
FV = 0
P/Y = 12 (months)
C/Y = (12 (months)
PMT: <u>END</u> | BEGIN
