Answer:
The 95.5% confidence interval would be given by (0.344;0.432)
Step-by-step explanation:
Previous concepts
A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".
The margin of error is the range of values below and above the sample statistic in a confidence interval.
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The population proportion have the following distribution
Solution to the problem
The estimated proportion on this case is given by:

In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 95.5% of confidence, our significance level would be given by
and
. And the critical value would be given by:
The confidence interval for the mean is given by the following formula:
If we replace the values obtained we got:
The 95.5% confidence interval would be given by (0.344;0.432)

Answer:
a) 101.125 gallons.
b) 3312 miles.
Step-by-step explanation:
You know that Jane's car will go 420 miles on 17.5 gallons of gasoline in highway driving, therefore:
a) You can calculate the number of gallons it will take to drive 2427 miles from her house to a friend's house as following:

b) You can calculate the distance the car can be driven on 138 gallons of gasoline as shown below:
