Hi,

Could someone please confirm that solutions for example 15B in the errata have some calculations errors in them.

I hope it's not just me. Losing the ability to use a calculator might cause some problems on exam day.

Title should have read example 15B

I can confirm that I believe there are calculation errors in the latest errata for this example. My calculator tells me that {\ln 1.05 - 0.0245 \over \sqrt{.001} } = .768122435 so that the answer to the first question is (SOA style) 1 - N(.77) = 1-0.7794= 0.2206. It also tells me that {\ln 1.05 - 0.245 \over \sqrt{.01} } = -1.962098358 so that the answer to the second question is 1 - N(-1.96) = .9750.

When it rains, it pours.
