Explanation / Answer

Note: While I'm not sure if you want to a full example ofeach, but based on the context that you provided here's eachstep. 1. Based on the empirical formula, 68% of the population scoresbetween -1 and 1, 95% of the population scores between -2 and2, and 99.7% of the population scores between -3 and 3. 2. The sample is assumed to be normally distributed, meaningthat there was no bias in terms of picking samples. Also, alarge sample size as well as randomly chosen samples isimplied. 3. H0: The difference between the mean and sample meanis not statistically significant. The mean falls within areasonable range from the population mean. 4. HA: The sample mean is significantly less/more thanthe population mean. 5. If we want to show that the treatment/procedure used in ourexperiment is either very effective or very ineffective. 6. HA: The difference between the sample mean andpopulation mean is significantly different. 7. If we want to show that the treatment used in ourexperiment somehow influences our sample. The sample mean isnot equal to the population mean.
