A consumer preference study compares the effects of three different bottle designs (A, B, and C) on sales of a popular fabric softener. A completely randomized design is employed. Specifically, 15 supermarkets of equal sales potential are selected, and 5 of these supermarkets are randomly assigned to each bottle design. The number of bottles sold in 24 hours at each supermarket is recorded. The data obtained are displayed in the following table. Bottle Design Study Data A B C 19...

IN C++ AS SIMPLE AS POSSIBLE ______ Re-write the given function, printSeriesSquareFifth,  to use a while loop (instead of for). • The function takes a single integer n as a parameter • The function prints a series between 1 and that parameter, and also prints its result • The result is calculated by summing the numbers between 1 and n (inclusive). If a number is divisible by 5, its square gets added to the result instead. • The function does not...
