<h2>Hello!</h2>
The answer is:
First, we need to find the money that Jarred needs including the money that he has already saved.
So, Jarred needs $800.
If he earns $160 a week, we can find the minimum weeks he has to work in order to earn $800 following the next steps:
So, if he has to work at least 5 weeks to earn the total amount of money, it can be expressed by the following inequality:
Have a nice day!

Answer:
The interval estimate for the population proportion of American adults who got their health insurance from an employer is (0.43, 0.47).
Step-by-step explanation:
The confidence interval is the interval estimate of the population parameter.
The confidence interval has a certain probability that the true value of the parameter is contained in the interval.
The general form of the confidence interval is:
Here,
SS = sample statistic.
MOE = margin of error
The sample statistic is an unbiased estimator of the population parameter. If the sample size is large enough then the sample statistic can be used to estimate the population parameter value.
In this case the parameter of interest is the population proportion of American adults who got their health insurance from an employer.
The information provided is:
<em>SS = p = </em>0.45.
<em>MOE</em> = 0.02.
Compute the confidence interval for the population proportion <em>p</em> as follows:
Thus, the interval estimate for the population proportion of American adults who got their health insurance from an employer is (0.43, 0.47).
