Express the confidence interval (0.036, 0.086) in the form of p-e< p

lina2011 [118]

Answer:

p-e< p < p+e

(0.061 - 0.025) < 0.061 < (0.061 + 0.025)

0.036 < 0.061 < 0.086

Step-by-step explanation:

Given;

Confidence interval CI = (a,b) = (0.036, 0.086)

Lower bound a = 0.036

Upper bound b = 0.086

To express in the form;

p-e< p < p+e

Where;

p = mean Proportion

and

e = margin of error

The mean p =( lower bound + higher bound)/2

p = (a+b)/2

Substituting the values;

p = (0.036+0.086)/2

Mean Proportion p = 0.061

The margin of error e = (b-a)/2

Substituting the given values;

e = (0.086-0.036)/2

e = 0.025

Re-writing in the stated form, with p = 0.061 and e = 0.025

p-e< p < p+e

(0.061 - 0.025) < 0.061 < (0.061 + 0.025)

0.036 < 0.061 < 0.086

How do I find the slope of the line containing the two points (9,0) and (-5,6)

deff fn [24]

Slope Formula: $\frac{y_2-y_1}{x_2-x_1}$

So using the slope formula, plug in the two points and solve for it as such:

$\frac{0-6}{9-(-5)}=-\frac{6}{14}\div \frac{2}{2}=-\frac{3}{7}$

<u>The slope is -3/7.</u>

According to a survey conducted by an environmental organization, the probability that an eligible voter cares strongly about en

Alina [70]

Answer:

The probability that the person cares strongly about environmental issues but does not vote regularly is P=0.33.

Step-by-step explanation:

We have:

Probability that the voter cares for the environment P(E)=0.63

Probability that the voter votes regularly P(R)=0.51

Probability that the voter votes regularly and cares for the environment P(R,E)=0.30

We have to calculate the probability that the voter cares for the environment but does not vote regularly P(not R, E).

We know that the probability that the voter cares for the environment is 0.63, and is divided between the ones that vote regularly and the ones that don't:

P(E)=P(R,E)+P(not R,E)=0.63

We also know that the probability that the voter votes regularly and cares for the environment is P(R,E)=0.30. Then:

P(E)=0.30+P(not R,E)=0.63

P(not R,E)=0.63-0.30=0.33

The probability that the person cares strongly about environmental issues but does not vote regularly is P=0.33.
