Find the indicated critical z value. Find zα/2 for α = 0.08
snow_lady [41]
Refer to the diagram shown below.
The value of z that yields the expected central area takes into account the excluded areas at both tails.

Half the tail area is α/2 = 0.08/2 = 0.04.
The central area is 1 - 0.04 - 0.04 = 0.92.

From standard normal tables, obtain
z(α/2) = 1.75

Answer: 1.75

Math Homework please help!

Answer:

30....:)

Step-by-step explanation:

So looking at the graph. L to the midpoint of K is 15.

lets ignore N.

The graph has a line between k to the midpoint of L.  So does L to the midpoint of k, which was 15.

This line means they are parrelel, so we can conlude that they both equal 15.

Adding the two together, we find KL is 30 in length.

The graph says KL is parrelel to JM.

So we can conclude that JM is 30.

<u>That looks like D on your answer sheet</u>

The only thing I am not sure of is what the N has to do with the answer.

They give you the value of N, and say the use N, however you do not need N to find the answer.

I think that the answer is 30, and it is included on the answer sheet as well. But fair warning that N did not have a use in it.

Hope this helps :)
