PLEASE HELP
Step 1: Parameter of interest
Ho: B1 = (
) versus H1: B1 ≠ 0
Step 2: Test statistic **use b1 = 1.6942,
ta/2 = 2.228, Σ(xi–x̄)2 = 1488.5625 and
so = 20.8577
sb1 = (
) Round to four decimal places and use to find
t-statistic
to = ( ) Round to four decimal places
Step 3: Classical approach
α = ( ), ta/2 = ( )
Round to three decimal places
Does the test statistic lie in the rejection region?
Step 4: P-value approach
p-value = ( ) Round to three decimal places
What is the relationship between p-value and α? p (>,
<) α
Step 5: Conclusion
Is there sufficient evidence to support the alternative
hypothesis? (Y/N)
Using the values above, construct a 95% confidence interval
for the slope of the true regression line, B1
