Determine the smallest sample size required to estimate the population meanunder the following specifications:
a. e = 2.4 confidence level = 80% databetween 50 and 150
d. e = 1.2 confidence level = 90%, data between 25 and 175
How do I find the third piece of information to use e= “Ï?” /(â??ð’?)?
How do I estimate the standard deviatiion?
