A city has a population of 250,000 people. Suppose that each year the population grows by 7.5%. What will the population be afte

Diano4ka-milaya [45]

So, if it grows by 6.75%, each year the population is 106.75% of the year before.

After 1 year, 370,000(1.0675). After two years, 370,000(1.0675)(1.0675).

370,000(1.0675)12 = your answer

In a poll, 37% of the people polled answered yes to the question "Are you in favor of the death penalty for a person convicte

Kay [80]

Answer:

The number of people surveyed was 330.

Step-by-step explanation:

The (1 - α)% confidence interval for the population proportion is:

$CI=\hat p\pm z_{\alpha/2}\cdot \sqrt{\frac{\hat p(1-\hat p)}{n}}$

The margin of error for this interval is:

$MOE= z_{\alpha/2}\cdot \sqrt{\frac{\hat p(1-\hat p)}{n}}$

The information provided is:

$\hat p=0.37\\MOE=0.05\\\text{Confidence level}=0.94\\\Rightarrow \alpha=0.06$

The critical value of z for 94% confidence level is, z = 1.88.

*Use a z-table.

Compute the value of n as follows:

$MOE= z_{\alpha/2}\cdot \sqrt{\frac{\hat p(1-\hat p)}{n}}$

$n=[\frac{z_{\alpha/2}\times \sqrt{\hat p(1-\hat p)}}{MOE}]^{2}$

$=[\frac{1.88\times \sqrt{0.37(1-0.37)}}{0.05}]^{2}\\\\=(18.153442)^{2}\\\\=329.5475\\\\\approx 330$

Thus, the number of people surveyed was 330.
