Step-by-step explanation:

The two points you're concerned with are (1, 3) and (4, 0). The average rate of change is

Answer:

a) 0.567

b) (0.5414,0.5926)

c) (0.5364,0.5976)

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 1007

Number of respondent that they will be able to afford health insurance in the future, x = 571

a) point estimate of the population proportion

$\hat{p} = \displaystyle\frac{x}{n} = \frac{571}{1007} = 0.567$

b) 90% Confidence Interval.

$\hat{p} + z_{\text{critical}}\times \sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

$z_{critical}\text{ at}~\alpha_{0.10} = \pm 1.64$

Putting values, we get,

$0.567 \pm 1.64\times \sqrt{\dfrac{0.567(1-0.567)}{1007}}\\\\0.567 \pm 0.0256=(0.5414,0.5926)$

c) 95% Confidence Interval.

$\hat{p} + z_{\text{critical}}\times \sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

$z_{critical}\text{ at}~\alpha_{0.05} = \pm 1.96$

Putting values, we get,

$0.567 \pm 1.96\times \sqrt{\dfrac{0.567(1-0.567)}{1007}}\\\\0.567 \pm 0.0306=(0.5364,0.5976)$
