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.
