Write a program that calls a function calculateSum to calculate the sum from 0 to N integers. The function calculateSum has one parameter N of type integer and returns an integer which represents the sum from 0 to N, inclusive. Write another function calculateAverage that calculates an average. This function will have two parameters: the sum and the number of items. It returns the average (of type float). The main function should be responsible for all inputs and outputs. Your functions will only calculate and return the values and NOT print anything. N is provided by the user; user input must be asked for repeatedly until a non-negative integer is provided.

Researchers measured the data speeds for a particular smartphone carrier at 50 airports. the highest speed measured was 78.1 mbps. the complete list of 50 data speeds has a mean of x overbarequals16.11 mbps and a standard deviation of sequals18.65 mbps. a. what is the difference between carrier's highest data speed and the mean of all 50 data speeds? b. how many standard deviations is that [the difference found in part (a)]? c. convert the carrier's highest data speed to a z score. d. if we consider data speeds that convert to z scores between minus2 and 2 to be neither significantly low nor significantly high, is the carrier's highest data speed significant? a. the difference is nothing mbps.
