Answer:

$67.20\%$

Step-by-step explanation:

Given

$n =2430$ --- sample

$r = 16.72\%$ --- degeneration rate

From the findings, we have:

$p = 377$ --- tested positive

$t =561$ --- total test

Required

The positive predicted value (PPV)

This is calculated using:

$PPV=\frac{Positive}{Total}$

i.e.

$PPV = \frac{377}{561}$

$PPV = 0.6720$

Express as percentage

$PPV = 0.6720 * 100\%$

$PPV = 67.20$
