Answer #1

The decision made by the researcher based on this information is to accept (fail to reject) the null hypothesis.

[explanation:-

test statistic :-

the critical value of z at alpha=0.05 is:-

the positive critical value indicates that it is a right tailed test .

decision:-

so, we fail to reject the null hypothesis.]

A researcher conducted a single-sample null hypothesis test with the z-statistic. The researcher reports that z = +1.30. This z-statistic was calculated from sample data that was drawn from a normal population. The researcher sets α = .05 and uses a two-tailed test. On the basis of his data, the researcher decides to fail to reject the null hypothesis. Did the researcher make the correct decision or did he make an error? If he made an error, what type of...

Based on the information provided for this hypothesis testing, what decision should you come to? (Assume that the population is normally distributed). Note that you need to complete the 5 step hypothesis testing. Be sure to include the cut-off sample score, the sample score on the comparison distribution, and the conclusion you reach. Mean=5, SD=1, Sample Score=7, .05 level of significance, one-tailed.
