(Will give brainliest)
kondaur [170]

Answer: C- Fail to reject the null hypothesis. There is not enough evidence to oppose the company's claim.

<u><em>Note: I'm not sure this is correct o_O </em></u>

I used a graphing calculator and calculated the t-interval of the jellybean sample using a 99% confidence level:

<em>tInterval 9.68,1.23,125,0.99</em>

It resulted in 9.68 ± 0.287805.

Therefore, we're 99% confident that the weight number of jellybeans would lie between 9.3922 oz and 9.9678 oz.

A weight of 9.45 oz lies within this range, therefore, it is possible that the candy company's claim is true.

A model of a baseball diamond is a square
Ilya [14]
Okay. So let’s break this down. We can solve this problem without a picture because it is a square. Therefore, all sides are the same. There are also four sides on a square. I have two ways to solve this problem.

One:
Divide 36 by 4 to know what each side is. 36/4 is 9. Since we are running from first to third, that is two sections of the field. Half of it. We would multiply 9 by 2. We get 18.

Two:
We know that from first to third is half the field. So we can do 36/0.5. This way, get 18

Answer: 18 inches
