Answer:
The 95% confidence interval for the true mean speed of thunderstorms is [10.712, 13.688].
Step-by-step explanation:
Given information:
Sample size = 10
Sample mean = 12.2 mph
Standard deviation = 2.4
Confidence interval = 95%
At confidence interval 95% then z-score is 1.96.
The 95% confidence interval for the true mean speed of thunderstorms is

Where,
is sample mean, z* is z score at 95% confidence interval, s is standard deviation of sample and n is sample size.



![CI=[12.2-1.488, 12.2+1.488]](https://tex.z-dn.net/?f=CI%3D%5B12.2-1.488%2C%2012.2%2B1.488%5D)
![CI=[10.712, 13.688]](https://tex.z-dn.net/?f=CI%3D%5B10.712%2C%2013.688%5D)
Therefore the 95% confidence interval for the true mean speed of thunderstorms is [10.712, 13.688].
You would get alternating interior and exterior angles, corresponding and consecutive angles, and vertical angles. There would be only two different angle measurements, which would add to 180 degrees, the degree of one straight line.
Answer:
Yes, the park should be expanded
Explanation:
180 adults said yes.
250 - 180 = 70
70 people thought the park shouldn't be expanded, but there are more people who want the mark to expand.
