Hello,
I am reviewing simple linear regression and am confused as to find one variable.
testing for significance t test
there is a formula given to find test statistic:
t= b1/sb1 (b sub one and s sub b1)
sb1 - is said to be the standard error of b1 - but where do I find that? in the data or is it part of the regression model?
Answer
Sb1 is the standard error for slope
this value is provided to you in the regression model, under the column Standard error(second column in regression table)
select the standard error corresponding to the slope coefficient beta1.
you will get your required value for standard error for slope or Sb1
b1 is the slope coefficient .

In a simple linear regression based on 25 observations, it is found that b1 = 0.51 and se(b1) = 0.28. Consider the hypotheses: [You may find it useful to reference the t table.] H0: β1 ≤ 0 and HA: β1 > 0. a-1. Calculate the value of the test statistic.
Consider the simple linear regression model: Suppose that the estimate of B1 based on a sample of 55 individuals is 2.3 and the corresponding standard error is 0.96. Test the null hypothesis H0: β1-0 vs HA: A 0 at the α-0.05 level and provide the corresponding p-value.

1. A researcher uses a simple linear regression to measure the relationship between the monthly salary (Salary measured in dollars) of data scientists and the number of years since being awarded a Master degree (Master Degree). A random sample of 80 observations was collected for the analysis. A researcher used the econometric model which has the following specification Salary,-β0 + β, Master-Degree, + εί, where i = 1, , 80 The (incomplete) Excel output of equation (1)...
In a simple linear regression based on 30 observations, it is found that b1 = 3.74 and se(b1) = 1.38. Consider the hypotheses: [You may find it useful to reference the t table.] H0: β1 = 0 and HA: β1 ≠ 0. a. Calculate the value of the test statistic. (Round your answer to 3 decimal places.)
The first photo is the data I
had collected in Minitab.I am confused on what the b1= to then get
the degree of freedom. I need this information to answer question
16 to plug in the right information in minitab to get t*multiplier.
Overall need help with getting the answer to #16 so then I can
continue the rest of the problems. Thanks! (also for 17 what is
S.E.)
