Question

Identify the null and alternative hypothesis(in symbolic and sentence form), test statistic, P-value(or critical values), conclusion about the null hypothesis, and final conclusion that addresses the original claim(Don’t just say Reject the null hypothesis or fail to reject the null hypothesis). If you used the calculator, identify everything mentioned above in addition to which calculator functions and inputs for each field were used.

3. As part of the National Heath and Nutrition Examination Survey, the Department of Heath and Human Services obtained self reported heights and measured the heights for males aged 12-16. All measurements are in inches. Is there a difference between the reported height vs. the measured height?

Reported Height 68 | 71 | 63 | 71 | 71 | 60 | 65 | 64 | 54 | 63 | 66 | 72
Measured Height 67.9 | 69.9 | 64.9 | 68.3 | 70.3 | 60.6 | 64.5 | 67.0 | 55.6 | 74.2 | 65.0 | 70.8
Difference ?,?,?,?,?,?,?,?,?,?,?,?

Answer 1

THIS IS A INDEPENDENT SAMPLE T TEST WITH FORMULA ,

H0 : THERE IS NO SIGNIFICANT DIFFERENCE BETWEEN REPORTED HEIGHTS AND MEASURED HEIGHTS.

H1 : THERE IS SIGNIFICANT DIFFERENCE BETWEEN REPORTED HEIGHTS AND MEASURED HEIGHTS.

AND USING EXCEL , DATA ANALYSIS TOOLPAK

AS P VALUE IS GREATER THAN ALPHA LEVEL (0.05) , WE FAIL TO REJECT THE NULL HYPOTHESIS , AND CONCLUDE THAT THERE IS NO SIGNIFICANT DIFFERENCE BETWEEN REPORTED AND MEASURED HEIGHTS.

I HOPE I WAS HELPFUL AND HAVE CLEARED YOUR DOUBTS.
