Please help to solve number 3 only
If the age of a sample of seven employees of a fast-food outlet (X) are as follows
19, 19, 65, 20, 21, 18, 20
1) Compute the best central measure and the best absolute dispersion measure.
2) If the oldest employee is retired, compute the best central measures and the best absolute dispersion measure.
3) If the employees in this outlet has a mean of age = 26 with variance between their ages as =16. Find the mean and the standard deviation of the age of employees of a fast-food in another outlet (Y), if the relation between them is as follows
Y = - 0.5 X + 35
Thanks in advance
i think Should i replace each value of Y with Xi i.e Y= 25.5, 25.5, 2.5, 25, 24.5, 26,25
