Answer:
(233.8436 ; 271.0564)
Yes
Step-by-step explanation:
Given :
Sample mean, xbar = 252.45
Sample standard deviation, s = 74.50
Sample size, n = 64
α = 0.05
The confidence interval :
Mean ± margin of error
Margin of Error = tα/2 * s/√n
df = n - 1 = 64 - 1 = 63
t(α/2, df = 63) = 1.998
Margin of Error = 1.998 * 74.50/√64
Margin of Error = 18.6064
The confidence interval :
252.45 ± 18.6064
(233.8436 ; 271.0564)
Comparing the confidence interval value and the mean value reported by the American Automobile Association ;it can be concluded that the mean reported by the American Automobile Association differ from the mean spent at Niagara Fall as 215.60 falls below the confidence interval.
Answer:

Step-by-step explanation:
Answer:

0.5 represent the original 100% but we want to obtain a 75% aditional so we can find for the value x if interest and we got:

So we need to sell the fries ar 0.875$ if we want to obtain a 75% of margin
Step-by-step explanation:
For this case we know that the french fries cost $0.50 and we want to have a margin of 75% on the fries. So we can use the following proportional rule:

0.5 represent the original 100% but we want to obtain a 75% aditional so we can find for the value x if interest and we got:

So we need to sell the fries ar 0.875$ if we want to obtain a 75% of margin
