When multiplying terms with the same base with exponents, you keep the base and add the exponents.
2^4 * 2^3 = 2^7
Any number with an exponent of zero equal one.
4^0 = 1
Multiply exponents when the term is being multiplied by a power.
(2^4)^3 = 2^12
When dividing terms with exponents, you keep the base and subtract the exponents.
9^7/9^5 = 9^2 9^5/9^7 = 1/9^2

Step-by-step explanation:
Answer:
The 95% confidence interval for the true proportion of all medical students who plan to work in a rural community is (0.0525, 0.1075).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of
.
For this problem, we have that:

95% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:
The upper limit of this interval is:
The 95% confidence interval for the true proportion of all medical students who plan to work in a rural community is (0.0525, 0.1075).
