requirements of a normal distribution. If the ratios are normally distributed then parametric statistics should be used and if they are not then a non parametric statistics should be used (2008). However‚ in order to determine if a sample or any group of data fits a standard normal distribution‚ the histogram and the Normal Probability Plot are the simplest ways to check whether or not it is reasonable to assume that the random errors inherent in the process have been drawn from a normal distribution

Then‚ if the sample size‚ n‚ is large enough‚ the distribution of the sample mean‚ x-bar will have a normal shape‚ the center will be the mean of the original population‚ m‚ and the standard deviation of the x-bars will be s divided by the square root of n.

Assuming that the distribution is normal for weight relative to the ideal and 99% of the male participants scored between ( - 53.68‚ 64.64)‚where did 95% of the values for weight relative to the ideal lie? Round your answer to two decimal places. Answer: Mean of weight relative to ideal = 5.48 and Standard Deviation (σ) = 22.93. Calculation: (x bar) 1.96(σ) 5.48± 1.96(22.93) 5.48 - 1.96(22.93)
