So first you need to by the chain saw and the chipper for $380. It should only take you about 9 hours to assemble it. And lets say that the 31 hours you were looking for the best of the best chain saw and chipper.
Answer:
B. the variability around the regression line.
Step-by-step explanation:
The standard errors represents the distance (how sparse) the observed values fall from the regression line.
Standard errors for regression are measures of the spread of variables around the average (regression line)
The standard error is dependent on the standard deviation of the observations and the reliability of the test.
When the test is perfectly reliable, the standard error is zero and when unreliable, it is equal to the standard deviation of the observations.
1) Average of six people = # of truffles / 6 = 7 ⇒ # of truffles = 6*7 = 42.
2) Average of first four people = # of truffles of the first four / 4 = 8 ⇒ # of truffles of the first four = 4*8 = 36
3) # of truffles of the fourth person = 11
4) # of truffles of the first three people = 36 - 11 = 25
5) # of truffles of the last three people = 42 - 25 = 17
Answer 17.
