To obtain the best point estimate of the proportion of all adults who say they are underpaid, divide the number of adults who stated they were underpaid by the total number of adults surveyed, multiply by 100, and convert to a percentage. Step 1: Divide the number of adults who reported being underpaid by the total number of adults polled. 284 557 = 0.509866220735786 Step 2: Multiply by 100 to get a percentage. 0.509866220735786 x 100 = 50.9866220735786% Rounding to the nearest full number yields 51%. So, the best estimate of the percentage of all adults who believe they are underpaid is 51%
