124 D . Ose given measurements for groups A, B, and C to answer the following: Group A: µ = 6, o = 2.5 Group B:u= 10.5,0=1.25 Group C: u = 8.7,0 = 3.2 d. List the groups in order for lowest mean to the highest mean. GroupA->Groupc ->Group B D. List the groups in order from Lowest variability to highest variability. Group B->Group C-> Craup A c.

Looking at group A, what percentage of the data fall between 3.5 and 8.5? b. Looking at group A, 99.7% of the data fall between what two values? а. 125 68%. 15 t0 13.5 c Looking at group A, what percentage of the data is greater than 8.5? 16/. Critical Thinking Questions: d. Suppose that a data in group A has a value of 11.5 and a data in group B has the same value of 11.5. Which data value is more extreme (further out from the mean) with respect to their own group, if any? Explain your answer. e. Suppose that a data in group A has a value of 2.1 and a data in group B has a value of 8.4. Which data value is more extreme (further out from the mean) with respect to their own group, if any? Explain your answer.
