Answer: Correct critical value = 2.2622
Step-by-step explanation:
Confidence interval for population mean when population standard deviation is unknown:
, where 
= sample mean, n= sample size, s= sample standard deviation, 
= two-tailed t value.
As per given: n= 10
degree of freedom : df = n-1=9
Critical t-value : 
So, the 95 percent confidence interval estimate for the mean :
The 95 percent confidence interval estimate for the mean:(190.14, 295.06)
Answer
17 m^3
Explanation
Volume of a given prism = bh
Where b = base area and h = height of prism
Base area = 1 • 2/2 (b • h /2)
= 1
Height = 17
17 • 1 = 17 m^3
Answer:
36 minutes
Step-by-step explanation:
150b / 8m = 18.75b/m we want to know how many bottle of water per minute
675b/18.75b/m = 36m
(1 gal, 2 qt, 3 pt) +
(1 gal, 3 qt, 7 pt) +
(1 gal, 3 qt, 3 pt)
= (3 gal, 8 qt, 13 pt)
= (3 gal, 14 qt, 1 pt)
= (6 gal, 2 qt, 1 pt)
The total volume of punch is 6 gallons, 2 quarts, 1 pint, or 6 5/8 gallons.
