Days with less than 8 hours of sleep
The tests do not tell us anything conclusive since all three tests are in agreement with both correlations
o The tests show that since there isn't strong agreement with the blue circle correlation, there must be agreement with the orange asterisk one
o The tests mean that a 3rd correlation must be necessary
The test at "20 days' shows that both correlations are true
QUESTION 2
If you fit a slope and intercept at the same time, then their errors will be correlated.
O True
O False
