I got a log-likelihood value of -34.82, so I am not getting whether the answer which I have got is right or not.
Can the likelihood take values outside of the range [0,1]?
Likelihood must be at least 0, and can be greater than 1.
Consider, for example, likelihood for three observations from a uniform on (0,0.1); when non-zero, the density is 10, so the product of the densities would be 1000.
Consequently log-likelihood may be negative, but it may also be positive.
[Indeed, according to some definitions the likelihood is only defined up to a multiplicative constant (e.g. see here), so even if the density were bounded by 1, the likelihood still wouldn’t be.]
