Write a matlab program that calculates the arithmetic mean, the geometric mean, and the root-mean-square average for a given set of values. your program must use 3 functions to calculate the 3 required means. the output should be formatted as follows:

your name statistical package arithmetic mean = x. geometric mean = x. rms average = x.

test your program on the following values: 1.1, 3.3, 3.00, 2.22, 2.00, 2.72, 4.00, 4.62 and 5.37. your main program calls 3 functions.

the data should be read by the main program from a text file, stored in an array and then passed to the functions.

the results and any other output should be printed by the main program. notice how the output results are aligned. also notice that the results are printed accurate to 5 decimal places.

do not use matlab built-in functions.

Ashielded metal arc-welding operation is accomplished in a work cell by a fitter and a welder. the fitter takes 5.5 min to load components into the welding fixture at the beginning of the work cycle, and 1.5 min to unload the completed weldment at the end of the cycle. the total ength of the weld seams 1200 mm, and the travel speed used by the welder averages 300 mm/min. every 600 mm of seam length, the welding stick must be changed, which takes 0.8 min. while the fitter is working, the welder is idle (resting): and while the welder is working the fitter is idle. (a) determine the average arc-on time as a fraction of the work cycle time. (b) how much improvement in arc-on time would result if the welder used flux-cored arc welding (manually operated), given that the spool of weld wire must be changed every 10 weldments, and it takes the welder 5.0 min to accomplish the change? (c) what are the production rates for these two cases (weldments completed per hour)? attach your work and solutions.
