Write a static method named countLastDigits that accepts an array of integers as a parameter and examines its elements to determine how many end in 0, how many end in 1, how many end in 2 and so on. Your method will return an array of counters. The count of how many elements end in 0 should be stored in its element at index 0, how many of the values end in 1 should be stored in its element at index 1, and so on.

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.
