Andrei [34K]

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:

H_0 : p = 0.3333\\\\H_a : p > 0.3333\\\\n = 150\\\\x = 64\\\\\hat{p} = \frac{x}{n} = \frac{64}{150} = 0.4267\\\\P_0 = 0.3333\\\\1 - P_0 = 1 - 0.3333 = 0.6667\\\\

z = \frac{\hat{p} - P_0}{[\sqrt{\frac{P_0 \times (1 - P_0 )}{n}}]}

   = \frac{0.4267 - 0.3333}{[\sqrt{\frac{(0.3333 \times 0.6667)}{150}}]}\\\\= 2.426

Calculating the right-tailed test:

P(z > 2.426) = 1 - P(z < 2.426) = 1 - 0.9924 = 0.0076\\\\P-value = 0.0076\\\\\alpha = 0.05\\\\P-value < \alpha

Therefore, we reject the null hypothesis.

This example shows that more than a third of the families own pets in this town.

Anarel [89]

Answer:

  • 0.3 or 30%

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>

  • 38 + 31 + 33 - 16*2 = 70

<u>Number of people using exactly one facility is:</u>

  • 100 - 70 = 30

<u>Probability of the person using exactly one facility is:</u>

  • 30/100 = 0.3 or 30%

Help me <br> Pls answer fast
stellarik [79]

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.
