A sample with size has , and . The dotplot for this sample is given below. A dotplot ranging from 58 to 95 with dots plotted as follows: 1 dot above 58, 1 dot above 68, 1 dot above 77, 1 dot above 81, 2 dots above 86, 1 dot above 90, 2 dots above 93, 5 dots above 94, and 4 dots above 95. Indicate whether or not it is appropriate to use the t-distribution. Choose the answer from the menu; Indicate whether or not it is appropriate to use the t-distribution. If it is appropriate, give the degrees of freedom for the t-distribution and give the estimated standard error. If it is not appropriate, enter in both of the answer fields below. Enter the exact answer for the degrees of freedom and round your answer for the standard error to two decimal places.

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
