Prove the following theorem indirectly. We will give you a start.

A triangle cannot have two right angles because the sum of all three angles of a triangle is 180. If there were two right angles in a triangle, then the two angles themselves would equal to 180 degrees, without adding the third angles. Since the degrees added up would have to equal 180 and with two right angles it would be more than 180, there cannot be two right angles in a triangle.

Answer: 2.511 lies in the rejection region, so we will reject the null hypothesis.

Step-by-step explanation:

Since the null and alternate hypothesis are :

$H_0:\pi =0.63\\\\H_1:\pi \neq 0.63$

Since there is 0.05 level of significance,

So, there will be two tail test:

As we know that

z = -1.96 or z = 1.96

If the test statistic does not fall in the range of -1.96 to 1.96, we will reject the null hypothesis.

So, it becomes,

$z=\dfrac{p-\pi }{\sqrt{\dfrac{\pi(1-\pi)}{n}}}\\\\z=\dfrac{0.7-0.63}{\sqrt{\dfrac{0.63.\times 0.37}{300}}}\\\\z=2.511$

Since 2.511 lies in the rejection region, so we will reject the null hypothesis.

Hence, People does not seem to be representative of the Pet Food survey respondents.
