Slope = (change in 'y') / (change in 'x')
If you find two points where the line goes through the corners of boxes,
then count up the 'y' boxes and the 'x' boxes between those two points,
you'll find that the line rises 3 y-boxes for each x-box.
The slope of the line is 3 .
Answer:
There is convincing evidence that less than 40% of US households plan to purchase television in the next two years.
Null hypothesis H•= 40%
Alternative Hypothesis Hi < 40%
Step-by-step explanation:
Null hypothesis H•= 40%
From the survey, percentage of household that responded that they plan to buy new television in the next two years is given by
= 374/1010 × 100%
= 37%
Therefore,
Alternative Hypothesis Hi<40%
Hence, there is convincing evidence that less than 40% of US households plan to purchase television in the next two years. Since both null and alternative Hypothesis are less than or equal to 40%.
Probability=number of specific outcomes/total number of possible outcomes...
P(GorB)=P(G)+P(B)
P(GorB)=3/20+5/20
P(GorB)=8/20=2/5 (40%)
Step-by-step explanation:
3,500×4×2/100= 280/100 = $2.80
