In​ 1964, paleontologists discovered the bones of a new species of dinosaur. The age of the dinosaur was estimated using​ potassium-40 dating of rocks surrounding the bones. Analysis of these rocks indicated that 88.7​% of the original amount of the​ potassium-40 was still present. The decay model for​ potassium-40 is Upper A equals Upper A 0 e Superscript negative 0.52912 t Baseline comma where t is in billions of years. Let Upper A equals 0.887 Upper A 0 in this decay model and estimate the age of the bones of the dinosaur.

From a survey, a reporter determined that the true estimate for the proportion of citizens who plan to sign a petition is between 68% and 74%. What is the survey’s margin of error?

Answers

Answer:

Therefore, the survey's margin of error is ±3%

Step-by-step explanation:

From a survey, a reporter determined that true estimate for the proportion of citizens who plan to sign a petition is between 68% and 74%.

given estimate range = 68% to 74%

Margin of error = (74% - 68%) ÷ 2

6 ÷ 2 = 3%

Therefore, the survey's margin of error is ±3%
±3% this was the answer from my test
