Question 3 1 pts Five standard solutions were analyzed by a method which gave signals according to the table. Signal Actual Concentration (mg/mL) 1.0 41 2.0 75 5.0 232 10.0 390 20.0 805 What is the sensitivity of this method? Answer should be rounded to nearest 0.1 (it should have one digit to the right of the decimal point). 34 Question 4 1 pts In the method from question 3, a sample of unknown concentration gave a signal of 372. What is the analyte concentration in the sample? [Again, round answer to nearest 0.1. And don't forget the y-intercept.] 10.9
