The confidence interval is (0.616, 0.686).

To find the confidence interval, we first find p, the proportion of students:
658/1010 = 0.6515

The confidence interval follows the formula
p\pm z(\sqrt{\frac{p(1-p)}{N}})

To find the z-score associated with this level of confidence:
Convert 98% to a decimal:  98% = 98/100 = 0.98
Subtract from 1:  1-0.98 = 0.02
Divide by 2:  0.02/2 = 0.01
Subtract from 1:  1-0.01 = 0.99

Using a z-table (http://www.z-table.com) we see that this is closer to the z-score 2.33.  

Using our information, we have:
0.6515\pm 2.33(\sqrt{\frac{0.6515(1-0.6515)}{1010}})
\\
\\0.6515\pm 0.0349

This gives us the interval (0.6515-0.0349, 0.6515+0.0349) or (0.616, 0.686).

ANSWERS AT THE BOTTOM!!<br> PLEASE HELP 10 POINTs!!
ZanzabumX [31]

Answer:

The slope is -1

Y-intercept is (0, -6)

Equation is y = -1x - 6 or y = -x - 6 either is right

Step-by-step explanation:

We already know that the slope is negative because the line is pointed this way \ pointed up to the left.

You have to do rise/run to find the slope.

The rise is 6 and the run is 6

6/6 = 1 since the line is negative the slope is -1x or -x

The y intercept is -6

Use the point (-2, -4)

Plug in

-4 = -(-2) + b

-4 = 2 + b (subtract 2 on both sides)

-6 = b

y = -x - 6

Hope this helps ya!!

Solve the system of linear equations below.
sergiy2304 [10]

Answer:

Step-by-step explanation:

Let's use the addition/elimination method to solve this.  If we multiply the first equation through by -1 we can eliminate the x terms.  Doing that gives us:

 -x  +  3y  =  3

  x  +  3y  =  9

The x's subtract each other away leaving us with

6y = 12 so

y = 2.

Now we will plug in 2 for y in either of the original equations to solve for x:

x + 3(2) = 9 and

x + 6 = 9 so

x = 3

The coordinate for the solution is (3, 2) or x = 3, y = 2

The second choice down is the one you want.
