Calculate the median and average of the student scores. Curve the student scores by adding the difference of 100 and the maximum score (100 - max) to each score. As a result, the new maximum score would become 100. Output the median and average scores with two digits after the decimal point. Output the curved scores as a NumPy array. End the last output with a newline. Follow the output format as shown in the example below. Note: Different input text files will be used by the auto-grader. The number of student scores in each file may vary. Ex: If the input of the program is: scores.txt the output is: Median = 73.00 Average = 73.32 Curved scores = [ 70 95 84 68 98 73 67 88 73 100 79 92 100 83 98 85 100 85 77 95 99 81 69 74 75]arrow_forwardProblem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive.

Close thefile.Now, go through the data in the array twice. Don’t go through all 10 elements in the array, only the elementsfor which you have read data. On the first pass, calculate the average of the numbers in the array. (Calculate thetotal, divide by count, that is µ).On the second pass through the data, for each number you should calculate how far it is from the average(number - average), square that, and keep a sum of the squares, that is S.When you’re done, calculate the average of that sum of squares, A. The square root of that number, σ is yourstandard deviation.Print out the average µ and standard deviation σarrow_forward
