complimentary angles, when added = 90 degrees

69 + 5n + 1 = 90

A 99% confidence interval for the difference between two proportions was estimated at 0.11, 0.39. Based on this, we can conclude
sladkih [1.3K]

Answer:

\hat p_1 -\hat p_2 \pm z_{\alpha/2} SE

And for this case the confidence interval is given by:

0.11 \leq p_1 -p_2 \leq 0.39

Since the confidenc einterval not contains the value 0 we can conclude that we have significant difference between the two population proportion of interest 1% of significance given. So then we can't conclude that the two proportions are equal

Step-by-step explanation:

Let p1 and p2 the population proportions of interest and let \hat p_1 and \hat p_2 the estimators for the proportions we know that the confidence interval for the difference of proportions is given by this formula:

\hat p_1 -\hat p_2 \pm z_{\alpha/2} SE

And for this case the confidence interval is given by:

0.11 \leq p_1 -p_2 \leq 0.39

Since the confidence interval not contains the value 0 we can conclude that we have significant difference between the two population proportion of interest 1% of significance given. So then we can't conclude that the two proportions are equal

Graph the inequality. -8 &lt; y + 2x &lt; 14
kap26 [50]

Answer:

Step-by-step explanation:

Split it into 2 inequalities:

-8 < y + 2x

y + 2x < 14

Isolate y , subtract 2x from first and then from second

-8 -2x < y

y < 14 -2x

Rewrite it so it looks pretty?

y > -2x-8

y < -2x +14

You can use the calculator to graph each inequality.

The solution or the system is the area where the 2 solutions for each line overlap.
