Here is the data output from a t-test analysis: Group Statistics Treatment group N Mean Std. Deviation Std. Error Mean Time of last visit in months A 19 9.74 3.557 .816 B 24 10.96 2.216 .452 Age in years A 19 50.74 16.993 3.898 B 24 51.17 16.325 3.332 Duration of disease A 19 1.32 .478 .110 B 24 1.25 .442 .090 Independent Samples Test Levene’s Test for Equality of Variances t-test for Equality of Means F Sig. t df Sig.

Write a persuasive report type essay. Describe the statistical test and the reason for using it. Briefly describe the summary statistics of the participants. What conclusions can you draw and what recommendations could you provide based on this information? In your analysis, and before providing your recommendations, please consider: ● group statistics ● the independent-samples t test ● homogeneity of variance ● probability that null hypothesis is correct ● t test limitations Justify your recommendations based on your data analysis. Include specific reasons for each recommendation.
