Answer:

The confidence interval is $0.2857< p < 0.4601$

Step-by-step explanation:

From the question we are told that

The sample size is n = 118

The number that gave the correct answer is k = 44

Generally the sample proportion is mathematically represented as

$\^ p = \frac{44}{118}$

=> $\^ p =0.3729$

Generally given that the confidence level is 95% the level of significance is mathematically represented as

$\alpha = (100 -95) \%$

=> $\alpha = 0.05$

Generally from the normal distribution table the critical value of $\frac{\alpha }{2}$ is

$Z_{\frac{\alpha }{2} } = 1.96$

Generally the margin of error is mathematically represented as

$E = Z_{\frac{\alpha }{2} } * \sqrt{\frac{p(1 - p)}{n} }$

=> $E = 1.96 * \sqrt{\frac{0.3729(1 - 0.3729)}{118} }$

=> $E = 0.0872$

Generally 95% confidence interval is mathematically represented as

$\r p -E < p < \r p +E$

=> $0.3729 -0.0872< p < 0.3729 +0.0872$

=> $0.2857< p < 0.4601$

Find the area of the shaded region.

densk [106]

[1]

A1 = (h (a + b)) / 2

A1 = (21 (17 + 32)) / 2

A1 = (21 x 49) / 2

A1 = 1,029 / 2

A1 = 514.5 mm²

[2]

A2 = (b x h) / 2

A2 = (11 x 9) / 2

A2 = 99 / 2

A2 = 49.5 mm²

[3]

The area of the shaded region =

A1 - A2 =

514.5 mm² - 49.5 mm² =

465 mm²

The answer is 465 mm².
