Answer:

YES

Step-by-step explanation:

Yes, the probability can be found through the binomial probability formula.

Binomial probability is used when there are two possible outcomes. The success (p) and failure (q) must be clear. Here, in the question if we need to find out the probability if live entertainment had increased the amount of money spent, then the percentage increase will be considered as success.

While if we want the probability that there is no change in the percentage of money spent, then it will be considered as failure.

WILL AWARD BRAINLIEST!!!
Anna007 [38]

Answer:

<u>A. p(hat) = .139</u>

We divide our sample population by the amount who tested positive. 14851/107109 = .139.

<u>B. 1.62 million</u>

We just multiply the p times the population. 11.69 M * .139 = 1.62 M

<u>C. No</u>

It depends upon the sample method. From what I can tell, I assume all conditions are met and it was not biased.

If it wasn't random, that is a problem, but we aren't given this information.

We can test if it's small enough. It can't be larger than 10% of the population. 107109 * 10 < 11.69 million, so it's small enough.

We can also test if it's large enough. np and nq must be greater than 10. 107100 * .139 > 10, 107100 * .861 > 10.
