The researcher uses the sample mean and correctly calculates

The researcher uses the sample mean and correctly calculates the test statistic to bez -2 .5 A researcher performs a hypothesis test at the = 0.05 level of significance. The null hypothesis is u = 0.85 and the alternative or alternate hypothesis is u0.85 and the p-value to be 0.0096. Based on these results, the researcher correctly decides to reject the null hypothesis Which statement correctly interprets the results of this hypothesis test? O The researcher has proven that the population mean is equal to 0.85. O The researcher has proven that the population mean is different from 0.85 The researcher has proven that the population mean is different from 0.85. O Evidence suggests that the population mean is different from 0.85 Evidence suggests that the population mean is 0.85.

Solution

1.As p < 0.05, then:

C. Evidence suggests that the population mean is DIFFERENT from 0.85. [ANSWER]

******************

Question 5:

The researcher may have rejected the null hypothesis when in reality the null hypothesis is true. [ANSWER, OPTION A]

*****************

It is alpha = 0.05. [OPTION B]
