Calculations are correct.

Should say in part b) input to 4 decimal places.
Display of table in statement could be tidied up.

Bill Foster commented on Unbiased estimator for exponential distribution 5 years, 11 months ago
In part a) the answer is to be input as 1/Y*(1-1/n), or (1/Y)(1-1/n). If the answer is input as 1/Y(1-1/n) then NUMBAS considers this as 1 over the function value Y(1-1/n). Is it not the case that a warning is usually given if the function is not recognised?

Bill Foster commented on Find the expectation and variance of three estimators of the mean 5 years, 11 months ago
Two problems:
- Suffices in part c) and in the solution are displayed as, for example, W_11.
- Sometimes the multiple choice display is in two rows rather than 1 row.
