Alocal charity believes they receive more money from people in the chevy chase area than from people in the alexandria area of washington dc. they conducted a survey of 24 people randomly selected form each area and recorded the results. at α = 0.01, what is the critical value of the test?

The critical value of the test is 2.807.

Step-by-step explanation:

Since we have given that

n = 24

So, the degree of freedom v = n-1 = 24 - 1=23

Since, n>30, so we will use 't-test'.

Here, α = 0.01

so, According to t-table, we get that

If we take α, then we are taking about two tail test.

If we take then we are talking about one tail test.

But in both the cases, the result will be same.

Hence, the critical value of the test is 2.807.

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.

multiply each one by 3.14
