If you pay more in tuition to go to a top business​ school, willit necessarily result in a higher probability of a job offer at​graduation? Let y=percentage of graduates with job offers andx=tuition ​cost; then fit the simple linear​model,E(y)=β0+β1x​,
to the data below. Is there sufficient evidence​ (α=0.10 of apositive linear relationship between y and​ x?

School | Annual tuition​ ($) | ​% with Job Offer |
---|
1 | 39,738 | 95 |
2 | 39,301 | 86 |
3 | 39,182 | 92 |
4 | 38,731 | 98 |
5 | 38,497 | 98 |
6 | 38,254 | 91 |
7 | 37,946 | 91 |

9 | 36,734 | 91 |

Give the null and alternative hypotheses for testing whetherthere exists a positive linear relationship between y and​ x?
A.H0​: β1s=0
Ha​:β1<0
B. H0​: β0=0
Ha​:β<0
C.H0​: β0=0
Ha​:β0>0
D. HO:β0:=0
Ha​: β0≠0
E. H0​: β1=0
Ha​: β1>0
F. H0​:β1=0
Ha​:β1≠0 .
Find the test statistic.
t=___________ ​(Round to two decimal places as​ needed.)
Find the​ p-value.​p-=______________ ​(Round to four decimalplaces as​ needed.)
Make the appropriate conclusion = ALPHA=0.10
Choose the correct answer below.
A.
Do not reject
H0. There is
insufficient
evidence that there exists a positive linear relationshipbetween y and x.
B.
Do not reject
H0.
There is
sufficient
evidence that there exists a positive linear relationshipbetween y and x.
C.
Reject
H0.
There is
insufficienti
evidence that there exists a positive linear relationshipbetween y and x.
D.
Reject
H0.
There is
sufficient
evidence that there exists a positive linear relationshipbetween y and x.
