In a study of simulated juror decision making, braden-maguire, sigal, and perrino (2005) investigated the type of verdict assigned given by study participants after they read a 12-page summation of a case involving a battered woman who had shot and killed her husband. of the 80 participants, 27 assigned gave the verdict of guilty, 49 gave the verdict of not guilty by reason of self-defense, and 4 gave the verdict of not guilty by reason of insanity. what type of chi-square statistical test should the researchers use to determine whether the distribution of verdicts differed from what could have been expected by chance?

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.

the answer is b
