Answer:
The correct option for the answer is C.) $3.29 / $2.96
Step-by-step explanation:
i) national average for a gallon of gas = $2.74
ii) for transportation New York is 1.2 times the National average
therefore one gallon of gas in New York will cost = 1.2 $2.74 = $3.29
iii)for transportation Los Angeles is 1.08 times the National average
therefore one gallon of gas in New York will cost = 1.08 $2.74 = $2.96
Therefore you should expect to pay for gas in New York versus Los Angeles C.) $3.29 / $2.96
Answer:
It is A. 35. All you have to do is multiply 120 by .35

Using the formula for margin of error as
MOE = z * σ / √n
would be very difficult since we are not given the value
of the standard deviation. Standard deviation value must be given since it is
obtained from the experiment.
However, we use another formula for MOE in the form of:
MOE = z sqrt [p (1 – p) / n]
where p is the proportion at 99% confidence interval at z
crit value. From the standard distribution tables, this corresponds to a p
value of:
z crit = 2.58
p = 0.9951
Therefore the margin of error is:
MOE = 2.58 sqrt [0.9951 (1 – 0.9951) / 670]
MOE = 6.96 x 10^-3 = 0.00696 s
We can see that at 99% Confidence interval, the Margin of
Error is extremely small (almost 0). For the sake of calculation:
Confidence interval = 4.7 s ± 0.00696 s
<span>Confidence interval = 4.69304, 4.70696</span>
