A student measures the period of a pendulum and obtains the following values Trial Time (s) 2.86 2.75 2.82 2.91 2.71 2.84 2.92 2.80 2.89 2.77 Time (s 2.98 2.82 2.69 2.84 2.91 3.02 2.99 2.83 2.79 2.76 Trial 12 13 14 15 16 17 18 19 20 10 (a) Create a PYTHON program to read in these values from a straight text datafile (trial number can be omitted from the input datafile) and find the mean, the sample variance, and the sample standard deviation, and standard error of the mean. (b) Estimate the probability that another single measurement will fall within 0.04 seconds of the mean. Why is this just an estimate
