Suppose that I scores have a bell-shaped distribution with a mean of 103 and a standard deviation of 15. Using the empirical rule, what percentage of I scores are between 73 and 133?

answer: this doesnt make any sense especially the photo.

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

idk what the heck he answer is, i’m just putting this here so i finish my account
