Relative Dispersion and Position Measures (Value: 45 points) (3 points each exercise). Instructions

After reading and analyzing the material presented in sections 2.3, 2.4 and 2.5, perform the exercises assigned for this activity, which will evaluate your learning on measures of variation or dispersion and relative position.

You must submit the necessary processes to support their response.With the following data from a sample: 720, 922, 613, 775, 580;

Find:

-Range Variance (Long Method)

-Standard Deviation

-Calculate the intervals used for the Empirical Rule:

Medium + S, Medium - S, Average +2S, Medium - 2S, Average - 3S, mean + 3S, using the mean and variance from the previous year.

With the following data: 0.8, 0.9, 1.3, 1.1, 1.2, 2.3, 2.6, 2.9, 2.4, 2.5, 3.0, 3.5, ; Calculate:

-Medium Range Standard Deviation (Using Method Approach Range)

-First Quartile

-Third Quartile

-IRQ

-Graph Stem

-Graph Sheet Box

-If the Mean of a dataset is 500 and the Variance is 36; calculate the intervals used for the for the Empirical Rule: Medium + S, Medium - S, Average +2S,

-Medium - 2S, Medium - 3S, Media + 3S. III. Assume that the Mean and Standard Deviation of a dataset are 40 and 5 respectively.

-What is the Z value for a value of X-50?
