<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u>
- To find the cost for 2 , 4 and 8 nails.
<u>Answer:</u><u>-</u>
According to the question ,
- Cost of 12 nails = $6
- Cost of 1 nail = $6/12
- Cost of 1 nail = $0.5
<u>Cost</u><u> </u><u>for </u><u>2</u><u> </u><u>nails </u><u>:</u><u>-</u>
- Cost of 2 nails = $0.5 *2 = $1
<u>Cost for 4 nails :-</u>
- Cost of 4 nails = $0.5 *4 = $2
<u>Cost for </u><u>8</u><u> </u><u>nails :-</u>
- Cost of 8 nails = $0.5 *8 = $4
Because they are all divided by 8 so you can put 2, 5, and 1 in the order so you will have:
5/8 > 2/8 > 1/8
so 5/8 is the greatest :)))

Answer: (72.535, 76.665)
Step-by-step explanation:
The confidence interval for population mean is given by :-

, where
= population standard deviation.
n= Sample size
= sample mean.
= Critical z-value (two-tailed)
Given : 
n= 81

The critical values for 90% confidence interval : 
Now, the confidence interval for population mean would be :

Hence, a 90 percent confidence interval estimatefor the average score of all students. : (72.535, 76.665)
