0.5p + 8 because the quarterback completed 8 more passes (the "+ 8" part) than half the number of passes he attempted (the "0.5p" part).

Construct a confidence interval of the population proportion at the given level of confidence.

scZoUnD [109]

Answer:

The lower bound of the confidence interval is 0.6922.

Step-by-step explanation:

We have to calculate a 94% confidence interval for the proportion.

The sample proportion is p=0.7167.

$p=X/n=860/1200=0.7167$

The standard error of the proportion is:

$\sigma_p=\sqrt{\dfrac{p(1-p)}{n}}=\sqrt{\dfrac{0.7167*0.2833}{1200}}\\\\\\ \sigma_p=\sqrt{0.000169}=0.013$

The critical z-value for a 94% confidence interval is z=1.8808.

The margin of error (MOE) can be calculated as:

$MOE=z\cdot \sigma_p=1.8808 \cdot 0.013=0.0245$

Then, the lower and upper bounds of the confidence interval are:

$LL=p-z \cdot \sigma_p = 0.7167-0.0245=0.6922\\\\UL=p+z \cdot \sigma_p = 0.7167+0.0245=0.7412$

The 94% confidence interval for the population proportion is (0.6922, 0.7412).

The sum of a number b and 7.5 is 4.8

andre [41]

B + 7.5 = 4.8
-7.5 -7.5
-----------------------
b = -2.7

Hope this helps!!!!!

You can also check your answer by doing replacing the number with the variable ( don't just write the anwser just because you know it, since its pre algebra you have to do it algebraically like above)

-2.7 + 7.5 = 4.8

Hope it helps!
