Can someone help me w this question? rq?
victus00 [196]

Answer:

C.

Step-by-step explanation:

We can off-the-bat eliminate choices A and B, because the first part of the quadratic formula is a -b. Therefore, the value for b in the quadratic has to be a positive, because the value in the formula is negative. This leaves us with choices C and D. If you look at the discriminant, you will see that our <em>a </em>in the quadratic formula is 3, so your answer choice is C.

In a large school district, 16 of 85 randomly selected high school seniors play a varsity sport. in the same district, 19 of 67
Mashcka [7]

Answer:

Standard Error of the difference = 0.0695

Step-by-step explanation:

Its given that : In a large school district, 16 of 85 randomly selected high school seniors play a varsity sport

\implies P_1=\frac{16}{85}\\\\n_1=85

Also, in the same district, 19 of 67 randomly selected high school juniors play a varsity sport

\implies P_1=\frac{19}{67}\\\\n_2=67

Now, finding the standard error of the difference :

\text{Standard Error = }\sqrt{\frac{P_1(1-P_1)}{n_1}+\frac{P_2(1-P_2)}{n_2}}\\\\\implies \text{Standard Error = }\sqrt{\frac{\frac{16}{85}(1-\frac{16}{85})}{85}+\frac{\frac{19}{67}(1-\frac{19}{67})}{67}}\\\\\implies\text{Standard Error = }0.0695

Hence, Standard Error of the difference = 0.0695
