Correct Answer - `{:("Across",,"Down"),("2. Data",,"1. Pictograph"),("5. Sector angle",,"3.Angle"),("6.Sectors",,"4. Bars"),("8. Three sixty",,"7. Line graph"),("10. Height",,"9.Width"),("11. Pie chart",,),("12. Bar graph",,):}`
Mean = 10
Number of observations=6
10=Sum/6
Sum = 60
One of the ways to obtain observations is we can write numeral 10 six times with sum 60.
Hence, the observations are 10,10,10,10,10,10
