Α = 1- (95/100) = 1-0.95 = 0.05
p = 1- α/2 = 1- 0.05/2 = 1-0.025 = 0.975
Degrees of freedom, df = Sample size -1 = 11-1 = 10
From t-tables, with cumulative probability pf 0.975 and df of 10,
Critical value = 2.228

Answer:
Exact Answer is 27/16
Decimal form: 1.6875
Mixed fraction 1 11/16 I assume that's what you need.
Step-by-step explanation:
27/16
Divide 27 by 16:
1 | 6 | 2 | 7
16 goes into 27 at most one time:
| | | 1
1 | 6 | 2 | 7
| - | 1 | 6
| | 1 | 1
Read off the results. The quotient is the number at the top and the remainder is the number at the bottom:
| | | 1 | (quotient)
1 | 6 | 2 | 7 |
| - | 1 | 6 |
| | 1 | 1 | (remainder)
The quotient of 27/16 is 1 with remainder 11, so:
Answer: 1 11/16
First you have to find a common denominator which is 4.
6 2/4 + 3 1/4 = 9 3/4
So your final answer is 9 3/4
Hope this helps!!!!
Company A : 15h + 20
Company B : 5h + 40
when would company B be cheaper....
15h + 20 > 5h + 40 ...put the less then sign towards Company B, then solve
15h - 5h > 40 - 20
10h > 20
h > 20/10
h > 2
Company B would be cheaper when the hours (h) are greater then 2
