Statistical Analysis and Hypothesis Testing in Experimental Research andPopulation Studies1.For a population with a standard deviation ofσ= 20, how large a sample is necessary tohave a standard error that is:a. less than or equal to 10 point?Letis the standard deviation of the population andis the size of the sample drawn.Letis the mean of the sample. Then the standard error of sample mean is defined as,.Here20 and10,MMnMnobtain the minimum required value of.2010101024 .Mnnnnnb. less than or equal to 4 points?Letis the standard deviation of the population andis the size of the sample drawn.Letis the mean of the sample.
