Discuss the benefits and disadvantages of using each of the three forms of a quadratic equation. If you need to use examples, you can input numbers into the three forms, but make sure you discuss both the benefits and disadvantages of each form. They are asking me to put this in a paragraph. Please help me!

Arandom sample of 15 observations is used to estimate the population mean. the sample mean and the standard deviation are calculated as 172 and 63, respectively. assume that the population is normally distributed. a. with 99 confidence, what is the margin of error for the estimation of the population mean? b. construct the 99% confidence interval for the population mean. c. construct the 95% confidence interval for the population mean. d. construct the 83% confidence interval for the population mean. hint: you need to use excel function =t.inv.2t to find the value of t for the interval calculation.
