Construct a spreadsheet to convert a nominal interest rate compounded m times per year i^(m) and convert it to an effective rate j_n per 1/n of a year. On the same spreadsheet, also start with an effective rate j_m per 1/m of a year and convert it to a nominal rate i⁽ⁿ⁾ compounded n times per year. Use your spreadsheet to solve the following two problems:

a. Given the nominal rate i⁽⁴⁾ = 8.950%, find the equivalent effective weekly rate.

b. Given the effective weekly rate j₅₂ = 0.170%, find the equivalent nominal rate i⁽⁴⁾.
