Answer:
a range of values such that the probability is C % that a rndomly selected data value is in that range
Step-by-step explanation:
complete question is:
Select the proper interpretation of a confidence interval for a mean at a confidence level of C % .
a range of values produced by a method such that C % of confidence intervals produced the same way contain the sample mean
a range of values such that the probability is C % that a randomly selected data value is in that range
a range of values that contains C % of the sample data in a very large number of samples of the same size
a range of values constructed using a procedure that will develop a range that contains the population mean C % of the time
a range of values such that the probability is C % that the population mean is in that range
Answer:
Age of Mark is 25 years.
Step-by-step explanation:
Let the current age of Mark = x years
After 20 years, age of Mark=(x+20) years
10 years ago,age of Mark was (x-10) years.
In 20 years Mark will be three times as old as he was 10 years ago.
=> ![\[(x+20) = 3*(x-10)\]](https://tex.z-dn.net/?f=%5C%5B%28x%2B20%29%20%3D%203%2A%28x-10%29%5C%5D)
=> ![\[(x+20) = 3x-30\]](https://tex.z-dn.net/?f=%5C%5B%28x%2B20%29%20%3D%203x-30%5C%5D)
=> ![\[(3x-x) = 30+20\]](https://tex.z-dn.net/?f=%5C%5B%283x-x%29%20%3D%2030%2B20%5C%5D)
=> ![\[(2x) = 50\]](https://tex.z-dn.net/?f=%5C%5B%282x%29%20%3D%2050%5C%5D)
=> ![\[x = \frac{50}{2}\]](https://tex.z-dn.net/?f=%5C%5Bx%20%3D%20%5Cfrac%7B50%7D%7B2%7D%5C%5D)
=> ![\[x = 25\]](https://tex.z-dn.net/?f=%5C%5Bx%20%3D%2025%5C%5D)
