Question
Consider the data set of the Quality of life and psychological adjustments. Consider the data set as a population data set (Not a sample).
Discuss and give the sampling distribution of x bar for a random sample of 16 participants selected from the given population. Assume the population is Normal.
Find the probability that x bar will be more than 8.2 AED [P (x bar 21.8 )]
Find the probability that X will be more than 8.2 AED [P (X 21.8 )]
Which result you trust more? explain
the data set is uploaded to this address https://files.fm/u/rdprqqgb please donwload the file

Explanation / Answer
For P(xbar<=21.8) we need to convert this to z as P(z<=21.8-mu/(sd/sqrt(n))
for P(x<=21.8)=P(z<=21.8-mu/sd)
i tried to download the data but not able to download. if u have data but the value and use this calculator to get the required probability. calculator is http://davidmlane.com/hyperstat/z_table.html
