Question
Consider the following competing hypotheses and accompanying sample data. (You may find it useful to reference the appropriate table: z table or t table )
Consider the following competing hypotheses and accompanying sample data.(You may find it useful to reference the appropriate table:ztableorttable) H0:p1p2 0 HA:p1p2< 0
x1= 255 | x2= 265 |
n1= 444 | n2= 444 |
a.Calculate the value of the test statistic.(Negative value should be indicated by a minus sign. Round final answer to 2 decimal places.)
b.Find thep-value. multiple choice 1
- 0.025p-value < 0.05
- 0.05p-value < 0.10
- p-value0.10
- p-value < 0.01
- 0.01p-value < 0.025
c.At the 10% significance level, what is the conclusion to the test? multiple choice 2
- Do not rejectH0since thep-value is greater than significance level.
- RejectH0since thep-value is greater than significance level.
- Do not rejectH0since thep-value is less than significance level.
- RejectH0since thep-value is less than significance level.
d.Interpret the results at= 0.10. multiple choice 3
- We cannot conclude that the population proportions differ.
- We conclude that the population proportions differ.
- We cannot conclude that population proportion 2 is greater than population proportion 1.
- We conclude that population proportion 2 is greater than population proportion 1.
