    true value and experimental value. Did they not give you these?

    really? maybe they want you to assume that the body temp is 37 Celsius

    it said body temp was 38.9 C

    was that supposed to be the measured temperature?

    The medicinal thermometer commonly used in the homes can be read (+or-) 0.1F, whereas those in the doctor's office may be accurate to (+or-) 0.1C, express the percent error expected from each of these thermometers in measuring a person's body temperature of 38.9C.

    ohh okay. So the true value is 38.9 C and the largest possible error is \(\pm0.1~^oC\) So \(\sf percent~error =\dfrac{|true-experimental|}{true}*100\%\) note that the absolute value bars and how it wont matter if you add or subtract 0.1 C from the value. For celsius it's: \(\sf percent~error =\dfrac{|38.9^oC-39~^oC|}{38.9^oC}*100\%\)

    what would the exp. be for F? 102.02 is true. so would exp. be 102.01?

    102.02 F +0.1 F = 102.12 F
