NEED ANSWERS TO BOTH
56% of students entering four-year colleges receive a degree within six years. Is this percent larger
than for students who play intramural sports? 152 of the 245 students who played intramural sports
received a degree within six years. What can be concluded at the level of significance of a = 0.05?
CUIGCI all answer ♥ the null hypothesis.
g. Thus, the final conclusion is that ...
O The data suggest the population proportion is not significantly larger than 56% 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 equa.
56%.
O The data suggest the population proportion is not significantly larger than 56% 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 larger
than 56%.
O The data suggest the populaton proportion is significantly larger than 56% 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 larger than 56%
h. Interpret the p-value in the context of the study.
O There is a 2.84% chance of a Type I error.
O If the sample proportion of students who played intramural sports who received a
degree within six years is 62% and if another 245 students who played intramural sports
are surveyed then there would be a 2.84% chance of concluding that more than 56% of
all students who played intramural sports received a degree within six years.
O If the population proportion of students who played intramural sports who received a
degree within six years is 56% and if another 245 students who played intramural sports
are surveyed then there would be a 2.84% chance that more than 62% of the 245
students surveyed received a degree within six years
O There is a 2.84% chance that more than 56% of all students who played intramural
