10. In preparation for constructing confidence interval for a population mean, it's important to plot the distribution of sample data. Below are stem plots describing samples from three different
populations. For which of the three samples would it be safe to construct a t-interval?

Sample Y
Sample z

(d) Sample X and Z
(c) None of the plots.

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

step-by-step explanation:

hope this is what you were asking for!

step-by-step explanation:

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

step-by-step explanation:

8*8*8*8*8*8*8*8*8*8*8*8=68719476736
