Build two beta prior distributions using the betaABfromModeKappa() function from the author.See Section 6.2 of the book.

(a) Suppose the sensitivity $P(+|D)$ of the rapid COVID-19 test is now being reported at 0.97.See the Further Reading.So there is some variability in this value according to experts.What values of $a$ and $b$ results from an expert opinion that the mode of the beta prior for sensitivity is 0.97 and that the opinion is worth 1000 data values.

(b) Suppose the sensitivity $P(+|D)$ of the rapid COVID-19 test is now being reported at 0.91.See the Further Reading.So there is some variability in this value according to experts.What values of $a$ and $b$ results from an expert opinion that the mode of the beta prior for sensitivity is 0.91 and that the opinion is worth 1000 data values.
