Answer:
A t-score of 2.0244 should be used to find the 99% confidence interval for the population mean
Step-by-step explanation:
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 39 - 1 = 38
Now, we have to find a value of T, which is found looking at the t table, with 38 degrees of freedom(y-axis) and a confidence level of 0.99(
). So we have T = 2.0244.
A t-score of 2.0244 should be used to find the 99% confidence interval for the population mean
5 pencils cost $.80. Each pencil costs $0.16
Then divide $0.16 into $0.40
This equals 2.5 pencils, you can't buy half a pencil

The three integers are 5,17 and -10
Step-by-step explanation:
Let x, y and z be three integers then
'The sum of the first and second integers exceeds the third by 32'
The third integer is 15 less than the first.
From Eqn 2:
Subtracting Eqn 1 from eqn 2
Dividing both sides by -2
Putting z=-10 in Eqn 3
Putting x=5 and z=-10 in Eqn 1
Hence,
The three integers are 5,17 and -10
