If it waters 1/18 of a lawn in 1/3 hours
then it waters 3/18 or 1/6 of a lawn in 1 hour
then 6 times (1/6) would be the full lawn
so 6 times (1) would be how many hours it would take
so it would take 6 hours
Answer:
And the expected value for a vector of zeros and the covariance matrix is given by:
So we can see that the error terms not have a variance of 0. We can't assume that the errors are assumed to have an increasing mean, and we other property is that the errors are assumed independent and following a normal distribution so then the best option for this case would be:
The regression model assumes the errors are normally distributed.
Step-by-step explanation:
Assuming that we have n observations from a dependent variable Y , given by
And for each observation of Y we have an independent variable X, given by
We can write a linear model on this way:
Where i a matrix for the error random variables, and for this case we can find the error ter like this:
