Answer:
The Sampling Distribution of the Sample Mean. If repeated random samples of a given size n are taken from a population of values for a quantitative variable, where the population mean is μ (mu) and the population standard deviation is σ (sigma) then the mean of all sample means (x-bars) is population mean μ (mu).
Step-by-step explanation:
Answer:
$ 68
Step-by-step explanation:
Let original value of a single share to be $ x
For 17 shares, total value of shares will be $17x
After a decrease of $4 per share, new value of a share will be $ x-4
For 17 shares, total value of shares after decrease will be $ 17(x-4) = 17x-68
Total change in the value of her stock will be ; value of shares before decrease-value of shares after decrease
= 17x-(17x-68)
=17x-17x+68
=68
