Question help the construction of the tminus−statistic for a oneminus− and a twominus−sided hypothesis

1 answer:

5 0

The construction for the two sided and one sided hypothesis is the same so the answer is letter d. the explanation behind this is: If you use a two-tailed test it just means that you need to allot half of your alpha to testing statistical significance. If your alpha is equal to 0.05, then this means that 0.025 must be in each tail of the distribution while for the one-tailed test, you will only allot your alpha in one-side.

Find the measure of each exterior angle of a regular 56-gon. Round to the nearest tenth.

Allisa [31]

Answer: The measure of each exterior angle is 6.4°.

Step-by-step explanation:

Since we have given that

Number of sides = 56

We have to find the measure of each exterior angles:

As we know the formula :

$\text{ measure of each exterior angle}=\frac{360^\cir}{\text{Number of sides}}\\\\\text{ measure of each exterior angle}=\frac{360}{56}\\\\\text{ measure of each exterior angle}=6.4^\circ$
