An advertising firm wanting to target people with strong desires for success conducted a study to see if such people differed in

the types of television shows they watched. Randomly selected participants recorded the shows they watched for a week, then their desire for success was assessed, and finally they were divided into two groups. Low Success seekers watched 8 comedies, 15 romances, 6 documentaries, 13 dramas, and 3 news shows. High Success seekers watched 3 comedies, 3 romances, 9 documentaries, 7 dramas, and 8 news shows.
1. Use the five steps of hypothesis testing.
2. Sketch the chi-square distribution. Be sure your sketch gives a rough indication of its shape and shows the cutoff score and the sample's score.
3. Explain the logic of what you have done to a person who is familiar with the logic and steps of hypothesis testing for the t test and analysis of variance, but who knows nothing about chi-square tests.
4. Figure a measure of effect size and indicate whether it is small, medium, or large.

Container A has 400 L of water,and is being filled at a rate of 8 liters per minute. Container B has 800 L of water,and is being
zepelin [54]

400+8x=800-6x.


Solving for x, you get 14x=400, and x is around 28.57


So it takes around 28.57 minutes for them to have the same amount of water.

A circle has a radius of length r. If you mark off the an arc on the circle of length 3r, what is the measurement of the angle t
prisoha [69]

Answer:

is 171.8 degrees

Step-by-step explanation:

Length of arc subtended by any angle \alpha with a radius r is given by \alpha *r.

For example

to calculate length of circumference  

angle subtended by whole circle is 2\pi

Therefore length of circumference is 2\pi *r

Similarly we can see that for semicircle angle at center is  \pi

hence length of arc is \pi r

____________________________________________

Given in the problem length of arc = 3r

radius= r

let the value of angle be \alpha

Plug in the value of length of arc in formula to calculate length of arc we have

3r = \alpha* r

\alpha = 3r/r = 3

This value of angle subtended is in radian, we need to convert radian into degrees.

_____________________________________

We know that \pi is equivalent to 180 degrees.

Also value of \pi is 3.14

hence 3.14 radian= 180 degrees

=>3.14/3.14 = 180/3.14 ----degrees dividing both side with 3.14

=> 1 radian = 57.325 degrees

=> 1*3 radian = 57.325 * 3 degrees( multiplying both side with 3 as we need to find value of 3 radian into degrees

=> 3 radian = 171.8 degrees.

the measurement of the angle that subtended by  the arc is 171.8 degrees or in radian 3 radian

If the ordered pair (x, y) is the solution for the system of equations, what is the value of y? x + y = 29 x + 2y = 12
Crank

Answer:

(46 , -17)

Step-by-step explanation:

hello :

x + y = 29...(*)

x + 2y = 12 ...(**)

multiply (*) by -1 : -x-y=-29   ...(***)

add (**) and(***) : y=-17

put this value in (*) : x-17 =29

so : x=46

one solution : (46 , -17)
