A population of values has a normal distribution with μ=68.9μ=68.9 and σ=72.8σ=72.8. You intend to draw a random sample of size n=43n=43.


FindP
₇₉, which is the mean separating the bottom 79% means from the top 21% means.




The mean =  (Use 1 decimal place)






Hint: First use page 3 of the standard normal distribution page to find the critical value ZcZc at 79%
Then use the formula Z=¯x−μ(σ√n)Z=x¯-μ(σn) to solve for ¯x
