Divide them
We'd get
2n^2+1/10n + 1
Answer:
For a sample size of 10, the t-value is about 3.25 (from tables) at a 99% confidence interval.
Explanation:
When the standard deviation for the population is not known, the confidence interval estimate for the population mean is performed with the Student's t-distribution.
The confidence interval for the mean is calculated as
![(\Bar{x}- t\frac{s}{\sqrt{n}} , \, \Bar{x}+ t\frac{s}{\sqrt{n}}](https://tex.z-dn.net/?f=%28%5CBar%7Bx%7D-%20t%5Cfrac%7Bs%7D%7B%5Csqrt%7Bn%7D%7D%20%2C%20%5C%2C%20%5CBar%7Bx%7D%2B%20t%5Cfrac%7Bs%7D%7B%5Csqrt%7Bn%7D%7D%20)
where
![\Bar{x}](https://tex.z-dn.net/?f=%5CBar%7Bx%7D)
= sample mean,
s = sample standard deviation,
t = t-value (provided in tables),
n = sample size.
When reading the t-value, (n-1) is called the df or degrees of freedom.
Had to look for the options and here is my answer.
Starting from the 1950s, both robberies and air pollution has increased and the conclusion that we can say regarding this increase is NOT JUSTIFIABLE. It is not justifiable because population is a different variable and they are not directly related to each other. Hope this helps.
So each basket hold 15 apples, and it says the baskets are full, so 5 x 15 = 75
4 of jonahs friends pick the same amount as jonah, so it would be 75 x 4 = 300.
So 375 apples is your awnser! Hope that helped!
