6. Temperature Conversion. Write a Python function that converts a temperature in Fahrenheit to temperature in Celsius. You can use two points of the form (F, C): (32, 0) and (212, 100) to find the genearl conversion formula.

7. Fibonacci Sequence. Fibonacci sequence has the following form: 1,1,2,3,5,8,13,21,... Write a non-recursive Python function Fib(n) that prints the first n terms in the Fibonacci sequence.

8. Assume you are given a list L of numerical data (integers or floating point number). Write a Python function that take list L as an argument and calculates the mean (average) of the

numerical values in the list L.

9. Assume you are given a list L of numerical data (integers or floating point number). Write a Python function that take list L as an argument and calculates the standard deviation of the numerical values in the list L.
