Answer:

C : does not have statistical significance

Step-by-step explanation:

Because there is a 15% chance of getting that many girls by chance, the method - does not have statistical significance.

By this method, the percentage of girls = 1067/2086=0.5115 or 51.15%

This type of method does not have practical significance.

Answer

6/-11

Step-by-step explanation:

use the slope formula m= \frac{y 2-y 1}{x 2-x 1}

then sub in numbers m=\frac{7-1}{-5-1}

now subtract numerator and the denominator

7-1= 6    and

-5-6=-11  this now looks like  \frac{6}{-11}

Given the points (5, 5) and (3, 7), write a linear equation that contains both in slope-intercept form.
zlopas [31]
First find slope
(7-5)/(3-5) = 2/-2 = -1
Slope intercept: y = mx + b
Y = -1x + b, plug in point
5 = -1(5) + b, b = 10
Equation: y = -1x + 10
