7 0

Answer:

1) null: π = 0.5, alternative: π > 0.5

2)p^= 80/124 =0.645

std error =(phat(1-phat)/n)1/2 =0.0430

3)z = (phat-p)/std erro =(0.645-0.5)/0.0430 =3.22

4)The observed proportion of couples who leaned to the right when kissing is 3.22 standard deviations above the null hypothesized value of 0.50

5)We have strong evidence that the proportion of couples that lean their heads to the right while kissing is more than 50%

I need help finding the slope

MAVERICK [17]

Answer:

slope = 1/4

Step-by-step explanation:

To find the slope, I chose two points where the line intersected the graph at an exact point.

Points:

(0, -8)

(4, -7)

Slope is the measure of rise over run, so starting at (0, -8) I went up one and to the right 4 times.

To put this as a fraction, we would have: 1/4

The numerator and denominator are positive because we went up and to the right.

Therefore, the slope is 1/4.
