A sample of 101 tobacco smokers who recently completed a new smoking cessation program were asked to rate the effectiveness of the program on a scale of 1 to 10, with 10 corresponding "completely effective" and 1 corresponding to "completely ineffective". The average rating for the sample was 4.1 and the standard deviation was 4.0. Construct a 95% confidence for the mean score. ​

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.

the answer is a.
