I. Use Bisection and False Position Method to locate the root of x³ - 2x + 1 = 0 betweenX = -2.2 and 2.2. Use 5 decimals in all values. Stop when absolute error is less than0.5%. Abs Error = ((Xr new - Xr old) / Xr new)* 100%. Please show samplecomputations for the 1st 3 iterations for X variables and the last 3 iterations for theAbs error computations.

The given function is fx=x3-2x+1. The given values of x are x=-2.2 and x=2.2 . The absolute error is…

A world wide fast food chain decided to carry out an experiment to assess the influence of income on number of visits to their restaurants or vice versa. A sample of households was asked about the number of times they visit a fast food restaurant (X) during last month as well as their monthly income (Y). The data presented in the following table are the sums and sum of squares. (use 2 digits after decimal point) ∑ Y = 393 ∑ Y2 = 21027 ∑ ( Y-Ybar )2 = SSY = 1720.88 ∑ X = 324 ∑ X2 = 14272 ∑ ( X-Xbar )2 = SSX = 1150 nx=8 ny=11 ∑ [ ( X-Xbar )( Y-Ybar) ] =SSXY=1090.5 PART A Sample mean income is Answer Sample standard deviation of income is Answer 90% confidence interval for the population mean income (hint: assume that income distributed normally with mean μ and variance σ2) is [Answer±Answer*Answer] 90% confidence interval for the population variance of income (hint: assume that income distributed normally with mean μ and variance σ2) is…
