Answer:
the equation of the least-squares line for the data is:
Step-by-step explanation:
In a simple linear regression model, such as, , the coefficients bo and b1 are estimated through the method of least squares by the use of the equations:
For the data provided you have to:
, thus:
the equation of the least-squares line for the data is:
Answer:
And i fwe look into the normalstandar dtable we can find the desired probability:
And then the The area to the right of z = 1.51 is 0.0655
Step-by-step explanation:
For this case we want to find the following probability:
And for this case we can use the normal standard distribution and the complement rule and we have this:
And i fwe look into the normalstandar dtable we can find the desired probability:
And then the The area to the right of z = 1.51 is 0.0655
