An insurer offers a coverage with a policy limit of 1500. The following four claims are observed on this coverage: 600 749 804 1250 It is also known that there are two additional claims for an amount over 1500 that are censored at 1500. An actuary models ground-up losses using an exponential distribution with parameter e = 1000. This model is tested against the experience using the Anderson-Darling A2 statistic. Calculate A2 and provide a conclusion about the acceptance-rejection level of the null hypothesis.

An insurer offers a coverage with a policy
limit of 1500. The following four claims are
observed on this coverage:
600 749 804 1250
It is also known that there are two
additional claims for an amount over 1500
that are censored at 1500.
An actuary models ground-up losses using
an exponential distribution with parameter
e = 1000. This model is tested against the
experience using the Anderson-Darling A2
statistic.
Calculate A2 and provide a conclusion
about the acceptance-rejection level of the
null hypothesis.
