A school reports that 83% of its graduates get jobs within one year. You take a random sample of 51
graduates, of whom 38 got a job within one year. Is this enough evidence to show that a significantly
smaller percent of graduates get jobs than advertised by the school? (Use a=0.01)
1. For this study, we should use Select an answWer
2. The null and alternative hypotheses would be:
Ho:?
Select an answer v
(please enter a decimal)
H: ? Select an answer v
(Please enter a decimal)
3. The test statistic
(please show your answer to 3 decimal places.)
%3D
4. The p-value =
(Please show your answer to 4 decimal places.)
5. The p-value is ? v a
6. Based on this, we should Select an answer v the null hypothesis.
7. As such, the final conclusion is that
O The sample data suggest that the population proportion is not significantly smaller than 83% at
a = 0.01, so there is not sufficient evidence to conclude that the percent of graduates get jobs
within one year is smaller than 83%.
O The sample data suggest that the populaton proportion is significantly smaller than 83% at a =
0.01, so there is sufficient evidence to conclude that the percent of graduates get jobs within
one year is smaller than 83%
