∑xi=40

∑yi=120

∑x^2i=200

∑y^2i=720

∑xiyi=86.4

Based on this calculate the following.

β^0=

.β^1=

The standard error for β^1 is:

The p-value for the test of no relationship is:

Answer #1

Formulae :

The standard error of   is :

where   predicted value of yi using regression equation

the t statistic is :

The p value is : 2 * P( T>t) where t is the observed value of t statistic.

You can see that to calculate beta 1 and beta 0 I need the value of n that is the sample size. and to calculate standard eror, p value I need all the values of x and y's so that I can calculate predicted values . Since it is not provided I can not solve it, but I have given you all the formulae you need. You can contact me for any more information in the comments. It will be my pleasure to help you!
