Answer:
For this case the confidence interval is given by :
Step-by-step explanation:
Data provided
represent the sample mean for the fuel efficiencies
population mean
s=2.51 represent the sample standard deviation
n=601 represent the sample size
Confidence interval
The formula for the confidence interval of the true mean is given by:
(1)
The degrees of freedom for this case is given by:
The Confidence level for this case is 0.95 or 95%, and the significance level 
and 
and the critical value is given by 
Replcing into the formula for the confidence interval is given by:
For this case the confidence interval is given by :
Yes because 6/18=1/3 and 2/6=1/3. Then 6/18=2/6
14.36 rounded to the nearest tenth is 14.4 (14.40).
Why?
Well because when rounding first we see what number we need to round. In this case it is 14.36 (3), next we look at the next number after the number which we need to round from which is 14..36 (6). If this number is 5 or MORE then we will round to the next number. But if it is LESS than 5 then we will keep it that number and add a 0 at the end. Since this number is AFTER 5 it will round up to 14.40.
So, 14.36 rounded to the nearest tenth is 14.40.
Hope I helped ya!!!
70 = 50 * x/100
x = 70/50*100 = 140
Seventh is 140% of 50.
