Answers are: c, d, e

--------------------------------

Explanation:

The inflection point is one where the graph changes from concave up to concave down, or vice versa. When x = c, the graph goes from concave down to concave up. For x = d, we go the opposite way from concave up to concave down. The value x = e is similar to x = c.

How many people aspire to become entrepreneurs if the total is 360 people? Doctor : 65% Police : 5% Pilot : 20% ENTREPENEURS????

KatRina [158]

Answer: 36 people

Step-by-step explanation:

1. The number of people that aspire to become doctor is:

360 people*0.65=234 people

2. The number of people that aspire to become police is:

360 people*0.05=18 people

3. The number of people that aspire to become pilot is:

360 people*0.2=72

4. The sum of people that do not aspire to become entrepreneurs is:

234 people+18 people+72 people=324 people

5. Therefore, the number of people that aspire to become entrepreneurs is:

360 people-324 people=36 people

The estimate of the population proportion should be within plus or minus 0.02, with a 90% level of confidence. The best estimate

Rudiy27

Answer:

The sample size required is 910.

Step-by-step explanation:

The confidence interval for population proportion is:

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

The margin of error is:

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

Given:

$\hat p = 0.16\\MOE= 0.02\\Confidence\ level =0.90$

The critical value of <em>z</em> for 90% confidence level is:

$z_{\alpha /2}=z_{0.10/2}=z_{0.05}=1.645$ *Use a standard normal table.

Compute the sample size required as follows:

$MOE=z_{ \alpha /2}\sqrt{\frac{\hat p(1-\hat p)}{n} }\\0.02=1.645\times \sqrt{\frac{0.16(1-0.16)}{n} }\\n=\frac{(1.645)^{2}\times 0.16\times (1-0.16)}{(0.02)^{2}} \\=909.2244\\\approx910$

Thus, the sample size required is 910.
