Afair four-sided die with four equilateral triangle-shaped faces is tossed 200 times. each of the die’s four faces shows a diferent number from 1 to 4.
a. find the expected value of the sample mean of the values obtained in these 200 tosses.
b. find the standard deviation of the number obtained in 1 toss.
c. find the standard deviation of the sample mean obtained in these 200 tosses.
d. find an approximate probability that the sample mean of the 200 numbers obtained is smaller than 2.7.

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

answer:

step-by-step explanation:

f(x)=2/3x-8, which give g(x) the greatest value.
