Answer:
The 99% confidence interval for the mean peak power after training is [299.4, 330.6]
![299.4\leq\mu\leq 330.6](https://tex.z-dn.net/?f=299.4%5Cleq%5Cmu%5Cleq%20330.6)
Step-by-step explanation:
We have to construct a 99% confidence interval for the mean.
A sample of n=7 males is taken. We know the sample mean = 315 watts and the sample standard deviation = 16 watts.
For a 99% confidence interval, the value of z is z=2.58.
We can calculate the confidence interval as:
![M-z\sigma/\sqrt{n}\leq\mu\leq M+z\sigma/\sqrt{n}\\\\315-2.58*16/\sqrt{7}\leq\mu\leq 315+2.58*16/\sqrt{7}\\\\315-15.6\leq \mu\leq 315+15.6\\\\299.4\leq\mu\leq 330.6](https://tex.z-dn.net/?f=M-z%5Csigma%2F%5Csqrt%7Bn%7D%5Cleq%5Cmu%5Cleq%20M%2Bz%5Csigma%2F%5Csqrt%7Bn%7D%5C%5C%5C%5C315-2.58%2A16%2F%5Csqrt%7B7%7D%5Cleq%5Cmu%5Cleq%20315%2B2.58%2A16%2F%5Csqrt%7B7%7D%5C%5C%5C%5C315-15.6%5Cleq%20%5Cmu%5Cleq%20315%2B15.6%5C%5C%5C%5C299.4%5Cleq%5Cmu%5Cleq%20330.6)
The 99% confidence interval for the mean peak power after training is [299.4, 330.6]
Answer:
hope it's help you ok have a good day
Answer: 7 feet
Step-by-step explanation:
Since all 4 sides of a square are equal, you do 28 / 4 = 7 feet, which is the answer.
Answer:
Step-by-step explanation:
6 is the thousands place
0 (right next to it) is the 10 thousands place
9 is the hundred thousands place. There is only 1 nine present so the answer is unique.
