Homework Statement
In the data table they are noon-hour temperatures of a certain week.
I calculated the mean which is 25 and l also calculated the standard deviation which is 3.74. Now they want me to show that :
if [tex]y=ax+b[/tex] then [tex]\bar{y}=a\bar{x}+b[/tex] and [tex]s_{y}= \left| a\right|s_{x}[/tex]
The Attempt at a Solution
I don't know where they get this y from. Can you give me hints on how to solve this question ?
