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.

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
