You have taken a sample and find a mean of 19.8 years. You wish to be very confident so you report an interval between 9.8 years and 29.8 years. This interval would certainly contain the true population mean and have a very high confidence level. Then: divide the decrease by the original number and multiply the answer by 100. % Decrease = Decrease ÷ Original Number × 100. If your answer is a negative number, then this is a percentage increase. If you wish to calculate the percentage increase or decrease of several numbers then we recommend using the first formula.f (x) = 2x3-12x² + 5 a) find intervalls) of increase & decrease (in interval notation) b) inflection points (2,-27) find where function concave up & down c) graph This problem has been solved!
