Can anyone actually help me work it out please
Answer:
3y=6x=18 the equation must look like this y=mx+b where m is the slope in this case it is 2 and b is the y-intercept 18 hope it helps
just divide every term by 3 to isolate y
(B) The population proportion of adults who watch 15 or fewer hours of television per week is 0.30.
(C) The population proportion of adults who watch 15 or fewer hours of television per week is less than 0.30.
(D) The population mean number of hours adults spend watching television per week is 15.
(E) The population mean number of hours adults spend watching television per week is less than 15.
The population proportion of adults who watch 15 or fewer hours of television per week is less than 0.30.
Given that,
A social scientist believed that less than 30 percent of adults in the United States watch 15 or fewer hours of television per week.
The scientist randomly selected 1,250 adults in the United States. The sample proportion of adults who watch 15 or fewer hours of television per week was 0.28,
And the resulting hypothesis test had a p-value of 0.061.
We have to determine,
The computation of the p- value assumes which of the following is true.
According to the question,
Let, The proportion of adults watching televisionless than or equal to 15% be = x
Null Hypothesis [H0] : x = 30% = 0.30
Alternate Hypothesis [H1] : x < 30% , or x < 0.30
P value is calculated at z value :
Where p' = 0.28, = 0.30, = 0.70 ;
Then,
Assuming 10% level of significance, p = 0.10
Therefore, p value 0.061 < 0.10, reject H0 & accept H1. This implies that we conclude that 'x i.e. proportion of adults watching television less than or equal to 15% < 30% or 0.30'
Hence, The population proportion of adults who watch 15 or fewer hours of television per week is less than 0.30.

Answer:
(C) The population proportion of adults who watch 15 or fewer hours of television per week is less than 0.30
Step-by-step explanation:
Let the proportion of adults watching television less than or equal to 15% be = x
P value is calculated at z value : p' - [ √ { p0 (1- p0) } / n ] ;
where p' = 0.28, p0 = 0.30, p1 = 0.70 ; ∴ p ( z < -1.543) = 0.061
Assuming 10% level of significance, p = 0.10
As p value 0.061 < 0.10, we reject H0 & accept H1. This implies that we conclude that 'x ie proportion of adults watching television less than or equal to 15% < 30% or 0.30'
Answer:
slope = -
Step-by-step explanation:
calculate the slope m using the slope formula
m =
let (x₁, y₁ ) = (6, 0 ) and (x₂, y₂ ) = (- 3, 2 )
substitute these values into the formula for m
m = = = -
Answer:
1/3
Step-by-step explanation:
First you have to do this step to find your slope: y2-y1/x2-x1
So your first point is (0,-4) (3,-3)
I got 1/3
You can also do rise over run as well
Answer:
Well It would about 1/10000000 if your talking about all colors, but its not specified how many blue regions other colored regions there are so I cant tell you without knowing.
Step-by-step explanation:
Just Take the amount of regions then put it under the amount of Blue regions there are then look up on a browser, Ex: What is 2/3 into a percent: 66.6 percent, And you have your answer :)
