If the rejection region is +1.10, what will be your decision if the z computed value is 2.34
IRINA_888 [86]

The decision when the z value is within the rejection region is that we'll have to reject the null hypothesis.

<h3>What is a rejection region?</h3>

It should be noted that the rejection region is also known as the critical region. It is the set of values where the null hypothesis is rejected.

When the observed test statistic is in the rejection region, we'll have to reject the null hypothesis and then accept rte alternative hypothesis.

How much more pizza is in a 12-in.diameter pizza than an 8-in.diameter pizza?
e-lub [12.9K]

Answer:

62.8 in2

Step-by-step explanation:

With round pizza we need to

find the area of each pizza in

square inches, then determine

the difference.  

The area of a circle is given by:

A = πr2

 

12 inch diameter, radius = 6

a = π(62) = 36π in2

 

8 inch diameter, radius = 4

a = π(42) = 16π in2

 

Difference:  36π - 16π = 20π in2

 

using 3.14 for pi, the difference is

20(3.14) = 62.8 in2

Gene starts from home and travels 3 miles north to the shopping mall. From the shopping mall, he travels 2 miles west to the lib
Alex73 [517]

Answer: The largest angle formed during his trip is at the mall between his home and the library.

Step-by-step explanation:

Hi, since the situation forms a right triangle (see image attached) the angle formed between his home and the library is 90°.

The sum of the interior angles of a right triangle is 180°, and the right angle (90°)is the largest angle formed.

So, the largest angle formed during his trip is at the mall between his home and the library.

Feel free to ask for more if needed or if you did not understand something.
