The following table shows descriptive summaries for data on the number of defective cars produced daily at a Chevrolet plant: Average = 5.34783 Minimum = 1.0 Median = 5.0 Maximum = 9.0 Mode = 5.0 Interquartile Range = 5.0 Variance = 6.78261 Variation coefficient = 48.6991% Standard deviation = 2.60434 If the data x = 9 is changed to an arbitrarily large data (for example, x = 100), of the following three statements, which one is true? a. The mean...
You have a data set C1 and you do the following transformation using statistical software: C2=C1/5 You find the mean, median and standard deviation of the original C1 and the new C2 and compare them. You must then answer the question pictured below. I assumed "none of them" would be the answer since all three values changed after the transformation, but that answer if wrong. •If you shift the original data (C1) as follows: C3=C1+5 how would you answer the...
