For the data set shown​ below
x  y
20Â Â 98
30Â Â 95
40Â Â 91
50Â Â 83
60Â Â 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 pointestimate for σ.
se=3.7771
​(Round to four decimal places as​ needed.)
​(c) Assuming the residuals are normally​ distributed, usetechnology 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 ofsignificance. Use the​ P-value approach.
Determine the​ P-value for this hypothesistest.
​P-value=__?__
​(Round to three decimal places as​ needed.)
