![51% of students entering four-year colleges receive a degree within six years. Is this percent different.
from for students who play intramural sports? 162 of the 275 students who played intramural sports
received a degree within six years. What can be concluded at the level of significance of a = 0.05?
a. For this study, we should use Select an answer
b. The null and alternative hypotheses would be:

H:? vSelect an answer v

c. The test statistic ? v =

d. The p-value =
(Please show your answer to 4 decimal places.)
e. The p-value is ? va
f. Based on this, we should Select an answer v the null hypothesis.
g. Thus, the final conclusion is that ...
O The data suggest the population proportion is not significantly different from 51% at a =
0.05, so there is not sufficient evidence to conclude that the population proportion of
students who played intramural sports who received a degree within six years is different
from 51%.
rse
O The data suggest the population proportion is not significantly different from 51% at a =
0.05, so there is sufficient evidence to conclude that the population proportion of students
who played intramural sports who received a degree within six years is equal to 51%.
O The data suggest the populaton proportion is significantly different from 51% at a = 0.05, so
there is sufficient evidence to conclude that the population proportion of students who played
intramural sports who received a degree within six years is different from 51%
h. Interpret the p-value in the context of the study.
OIf the sample proportion of students who played intramural sports who received a degree
within six years is 59% and if another 275 voters are surveyed then there would be a
0.85999999999999% chance that we would conclude either fewer than 51% of all students who
played intramural sports received a degree within six years or more than 51% of all students
who played intramural sports received a degree within six years.
O There is a 0.85999999999999% chance that the percent of all students who played intramural
sports who received a degree within six years differs from 51%.
