If you pay more in tuition to go to a top business school, will it necessarily result in a higher probability of a job offer at graduation? let yequalspercentage of graduates with job offers and xequalstuition cost; then fit the simple linear model, upper e (y )equals beta 0 plus beta 1 x, to the data below. is there sufficient evidence (at alphaequals0.10) of a positive linear relationship between y and x? school annual tuition ($) % with job offer 1 39 comma 696 97 2 39 comma 282 84 3 39 comma 043 87 4 38 comma 905 99 5 38 comma 855 85 6 38 comma 005 87 7 37 comma 461 95 8 37 comma 413 93 9 37 comma 293 81 10 37 comma 226 88 give the null and alternative hypotheses for testing whether there exists a positive linear relationship between y and x?
a. upper h 0: beta 0equals0 upper h subscript a: beta 0not equals0
b. upper h 0: beta 1equals0 upper h subscript a: beta 1not equals0
c. upper h 0: beta 0equals0 upper h subscript a: beta 0less than0
d. upper h 0: beta 0equals0 upper h subscript a: beta 0greater than0
e. upper h 0: beta 1equals0 upper h subscript a: beta 1greater than0 your answer is correct.
f. upper h 0: beta 1equals0 upper h subscript a: beta 1less than0 find the test statistic. tequals nothing (round to two decimal places as needed.)
