Explanation / Answer

The number of sample observations lies between 0.65 to 6.47 is 33

The actual percentage is 33/43 = 0.7674 =77%

The number of sample observations lies between -2.26 to 9..38 is 41

The actual percentage is 41/43 = 0.95349 = 95%

The number of sample observations lies between -5.17 to 12.29 is 42

The actual percentage is 42/43 = 0.9767 = 98%

and

Tchebysheff : Atleast 1-(1/k2) = 1 - (1/12) = 0%

Finally,
