Question

For the data set shown​ below

x   y
20   98
30   95
40   91
50   83
60   70

​(a) Use technology to find the estimates of β0 and β1.

β0 ≈b0=114.60

​(Round to two decimal places as​ needed.)

β1≈b1=−0.68

​(Round to two decimal places as​ needed.)

​(b) Use technology to compute the standard​ error, the point estimate for σ.

se=3.7771

​(Round to four decimal places as​ needed.)

​(c) Assuming the residuals are normally​ distributed, use technology to determine sb1.

sb1equals=0.1194​

(Round to four decimal places as​ needed.)

​(d) Assuming the residuals are normally​ distributed, test H0: β1=0 versus H1: β1≠0 at the α=0.05 level of significance. Use the​ P-value approach.

Determine the​ P-value for this hypothesis test.

​P-value=__?__

​(Round to three decimal places as​ needed.)

Answer 1

from above

p value =0.011
