Answer:
The answer is "The null hypothesis was rejected".
Step-by-step explanation:
Following are the right-tailed test:
Calculating the null and alternative hypothesis:

![= \frac{0.4267 - 0.3333}{[\sqrt{\frac{(0.3333 \times 0.6667)}{150}}]}\\\\= 2.426](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B0.4267%20-%200.3333%7D%7B%5B%5Csqrt%7B%5Cfrac%7B%280.3333%20%5Ctimes%200.6667%29%7D%7B150%7D%7D%5D%7D%5C%5C%5C%5C%3D%202.426)
Calculating the right-tailed test:

Therefore, we reject the null hypothesis.

Look at the problem and do it in order
Answer:
Step-by-step explanation:
<u>Number of people using more than one sport facility:</u>
- 38 - gym and pool
- 31 - pool and track
- 33 - gym and track
- 16 - all three
<u>Since 16 is counted for all three, total number of those using more than one facility is therefore:</u>
<u>Number of people using exactly one facility is:</u>
<u>Probability of the person using exactly one facility is:</u>
Answer:
The answer is 42/19 or 2 4/19
Step-by-step explanation:
You have to divide 7 by 19/6. I say "19/6" because that's an improper fraction. You do " 7/1 divided by 19/6". Then you do KCF (Keep Change Flip). So you do "7/1 times 6/19". So now you just multiply across. And there's your answer (42/19) If you want to do a mixed number then you get 2 4/19.
