Sp3 hybridization azimuthal quantum number

TL;DR Summary

azimuthal quantum number for sp3 hybridization

The s orbital corresponds to l=0
The p orbital corresponds to l=1

For an electron in an sp3 hybridization orbital what is l?

The answer appears to be 1.5 but I don't know why

Where is that from?

sp3 hybrid orbitals are not eigenstates of the orbital angular momentum operator, so it makes no sense to talk about their $l$ value.

I am simply noting that the numbers match the image below it.

And I am no longer sure that it is an image of sp3 hybridization. It might be something else
