Answer:
We want to construct a confidence interval at 99% of confidence, so then the significance level would be and the value of
. And for this case since we know the population deviation is not appropiate use the t distribution since we know the population deviation and the best quantile assuming that the population is normally distributed is given by the z distribution.
And if we find the critical value in the normal standard distribution or excel and we got:
And we can use the following excel code:
"=NORM.INV(0.005,0,1)"
Step-by-step explanation:
For this case we have the following info given:

Answer: Option 'B' is correct.
Our net price will be $3357.21.
Explanation:
Since we have given that
The list price of set of saws = $3800
There are 3 successive discounts :
8%,3%,1%
So, if we apply first for 8% discount our new price becomes,
Now, if we apply 3% on our deducted price , our new price becomes ,
Now, we'll apply for 1% on our new deducted price , our net price becomes,
Hence, our net price will be $3357.21.
Therefore, Option 'B' is correct.
