Find the point estimate for the situation below. Texas Instruments claims that its calculators are used in 95% of all classrooms. A random
sample of 140 classrooms showed that they are used in 93% of classrooms. Suppose we
are using a 0.05 level of significance.
O 140
0.05
0.95
0.93

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.
