Hey can I please have help with this, the data values are below:

Devise a null and alternative hypothesis, then perform a one sample z-test using alpha=O.05 if our class is taller or shorter than the average human in the United States. Graphically display your answer and statistically write up results. In addition, determine the effect size of this relationship and interpret. Notes: 1. The average height of adults in the United States is 67.03.8 inches. (Note: this is a population SD) 2. Calculate and interpret the effect size (use Cohen's d): Cohen's d = (Msample - upogulation) / o)
