Answer:
cubic
Step-by-step explanation:
The degree of a term with one variable is the exponent of that variable. When there is no exponent, the degree is 1. When there is no variable, the degree is 0.
The degrees of the terms in this expression are, left to right, ...
2, 3, 1, 0
The largest of these numbers is the degree of the polynomial: 3.
A polynomial of degree 3 is called a cubic.
___
<em>Comment on degree names</em>

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).
