Answer:
p value = 0.3122
Step-by-step explanation:
Given that Pedro thinks that he has a special relationship with the number 3. In particular,
Normally for a die to show 3, probability p = ![\frac{1}{6} =0.1667](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B6%7D%20%3D0.1667)
Or proportion p = 0.1667
Pedro claims that this probability is more than 0.1667
![H_0 = P =0.1667______H_a = P>0.1667_____](https://tex.z-dn.net/?f=H_0%20%3D%20P%20%3D0.1667______H_a%20%3D%20P%3E0.1667_____)
where P is the sample proportion.
b) n=30 and ![P = 6/30 =0.20](https://tex.z-dn.net/?f=P%20%3D%206%2F30%20%3D0.20)
Mean difference = ![0.2-0.1667=0.0333](https://tex.z-dn.net/?f=0.2-0.1667%3D0.0333)
Std error for proportion = ![\sqrt{\frac{p(1-p)}{n} } \\=0.0681](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7Bp%281-p%29%7D%7Bn%7D%20%7D%20%5C%5C%3D0.0681)
Test statistic Z = p difference/std error = 0.4894
p value = 0.3122
p >0.05
So not significant difference between the two proportions.
Answer:
The train would travel 880 km in 11 hours.
Step-by-step explanation:
Hey there!
A state border is thousands of miles long (some of them). Meters would be too small of a measurement. Centimeters is even smaller. So the answer is B. Because this uses the least amount of numbers.
I hope this helps!
Answer:
Rockefeller HS = 31%
Clayton West = 51%
Clayton South = 18%
Step-by-step explanation:
Given the following:
Championship wins shared by 3 basketball teams :
Rockefeller HS = 12
Clayton West = 20
Clayton South = 7
Percentage of total wins each team has :
Total number of wins = (12 + 20 + 7) = 39 wins
Percentage wins :
[(Number of wins per team) / total number of wins)] × 100
Rockefeller HS:
(12 / 39) * 100 = 30.769% = 31%
Clayton West :
(20/39) * 100 = 51.28% = 51%
Clayton South:
(7/39) * 100 = 17.948% = 18%
