Hey Mike, could you please help me with practise test 8, section 4 question 38? If you simply plug in P as 152, it’s easy to get the answer. However, im not sure what “if P approximates the values in the table to within 10 micrograms per milliliter” exactly means? How does that statement help me to solve the question or change the numbers I’m inputting as P?

Thank you so much!
