I have a data set containing scores from 1- 100 but all of them are only between 80-100. SO I want to set 80 as the minimum score(like a 1 on a scale)
I want to convert these scores into a more accurate measure on a scale of 1 - 10
is it possible to do so? and if so then how?

(Statistics) a. Write a C++ program that reads a list of double-precision scores from the keyboard into an array named scores. It is assumed that the user will enter no more than 35 scores. The scores are to be counted as they're read, and entry is to be terminated when a negative value has been entered. After all scores have been input, your program should find and display the sum and average of the scores. The scores should then be...

7. Differentiating normal z scores from all z scores Aa Aa Recall that z scores have the same shape as the original raw scores. That is, if the the raw scores are normally distributed, then when you transform them to z scores, these z scores are also normally distributed. Here we will cal such normally distributed z scores "normal z scores. Consider the following statements. Some of these statements are necessarily true for all z scores, some of these statements...

Write a program that instantiates an array of integers named scores. Let the size of the array be 10. The program then first invokes randomFill to fill the scores array with random numbers in the range of 0 -100. Once the array is filled with data, methods below are called such that the output resembles the expected output given. The program keeps prompting the user to see if they want to evaluate a new set of random data. Find below...
