Suppose you are given an unknown chip which could be any one of the of the following: 7400, 7402, 7404, 7408, 7410, 7420, 7427,7432,7486. You must prepare a detailed, logical, efficient plan to identify your chip without damaging it. Hint: "Try all the input combinations for all the chips until I find the right one" is not a detailed, logical, efficient plan Prelab: Have a well thought out plan for your experiment. This should be typed with detailed instructions for how you plan to run your experiment to identify unknown chips. In the Lab: The TA will give you a 2 chips each labeled with a letter. You will need to use your well thought out plan to identify the unknown chips. (A large portion of your grade depends on the design of your experiment. Simply identifying the chip will not receive full credit. You will need to have a well documented plan for how to identify the unknown chip

1. the program must provide following functions to extract some statistics. note that the data_list parameter specified in these functions may be the same for all functions or different for different functions—that is your choice. a skeleton file is provided on mirmir. a) open_file()prompts the user to enter a year number for the data file. the program will check whether the year is between 1990 and 2015 (both inclusive). if year number is valid, the program will try to open data file with file name ‘year. txt’, where is the year. appropriate error message should be shown if the data file cannot be opened or if the year number is invalid. this function will loop until it receives proper input and successfully opens the file. it returns a file pointer and year. i. hint: use string concatenation to construct the file name b) read_file(fp)has one parameter, a file pointer read. this function returns a list of your choosing containing data you need for other parts of this project. c) find_average(data_list) takes a list of data (of some organization of your choosing) and returns the average salary. the function does not print anything. hints: i. this is not the average of the last column of data. it is not mathematically valid to find an average by finding the average of averages—for example, in this case there are many more in the lowest category than in the highest category. ii. how many wage earners are considered in finding the average (denominator)

Assume that there is a 4% rate of disk drive failure in a year. a. if all your computer data is stored on a hard disk drive with a copy stored on a second hard disk drive, what is the probability that during a year, you can avoid catastrophe with at least one working drive? b. if copies of all your computer data are stored on three independent hard disk drives, what is the probability that during a year, you can avoid catastrophe with at least one working drive?
