Answer:
The confidence interval at a 90% confidence level is ($43.79, $48.21).
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 Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find M as such
In which is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the mean subtracted by M. So it is 46 - 2.21 = 43.79
The upper end of the interval is the mean added to M. So it is 46 + 2.21 = 48.21.
The confidence interval at a 90% confidence level is ($43.79, $48.21).

Answer:
The value of K is 5
Step-by-step explanation:
I reversed it.
The tiny squares means 90⁰, so 90+49=139
All of these angles add up to 180⁰
So 180-139=41
The k equation equals 41⁰, so reverse it to find answer
41-1=40
40÷8=5
