... Assumptions for Using Z CI • Sample: simple random sample • Sample Population: sample size must be large (n ≥ 30) or the population must be normally distributed. Dot plots, histograms, normality plots and box plots of sample data can be used as evidence if population is not given as normal • Popula ...

... 4. The manager of a store wants to find whether the mean unpaid balance is more than $400. The level of significance is set at 0.05. A random sample of 60 unpaid balances revealed the sample mean is $407 and the standard deviation is $22.50. Should she conclude that the mean is greater than $400? 5. ...

Coefficient of Variation:
... It is often difficult to use our standard deviation formula to compare measurements from different populations. Due to this fact, statisticians produced the coefficient of variation. The coefficient of variation expresses the standard deviation as a percentage of what is being measured relative to t ...
