Question: Rosetta continues her hypothesis test, by finding critical values and making a conclusion about the null hypothesis. H0:=47.4; Ha:>47.4, which is a right-tailed test. =0.05.

Rosetta continues her hypothesis test, by finding critical values and making a conclusion about the null hypothesis.

  • H0:=47.4; Ha:>47.4, which is a right-tailed test.
  • =0.05.
  • z0=0.561

Which is the correct conclusion of Rosetta's one-mean hypothesis test at the 5% significance level?

z0.101.282z0.051.645z0.0251.960z0.012.326z0.0052.576

Use the above table of common values for the critical values.

Select the correct answer below:

Critical value: z0.05=1.645. We should reject H0. So, at the 5% significance level, the data provide sufficient evidence to conclude that the new technique helped Rosetta get more distance on each throw.

Critical value: z0.05=1.645. We should reject H0. So, at the 5% significance level, the data provide sufficient evidence to conclude that the new technique helped Rosetta get more distance on each throw.

Critical value: z0.05=1.645. We should not reject H0. So, at the 5% significance level, the data do not provide sufficient evidence to conclude that the new technique helped Rosetta get more distance on each throw.

Critical value: z0.025=1.96. We should reject H0. So, at the 5% significance level, the data provide sufficient evidence to conclude that the new technique helped Rosetta get more distance on each throw.

Critical value: z0.05=1.645. We should not reject H0. So, at the 5% significance level, the data do not provide sufficient evidence to conclude that the new technique helped Rosetta get more distance on each throw.

Critical value: z0.025=1.96. We should not reject H0. So, at the 5% significance level, the data do not provide sufficient evidence to conclude that the new technique helped Rosetta get more distance on each throw.
