Write a Python function isPrime(number) that determines if the integer argument number is prime or not. The function will return a boolean True or False. Next, write a function HowManyPrimes(P), that takes an integer P as argument and returns the number of prime numbers whose value is less than P. And then write a function HighestPrime(K) that takes integer K as an argument and returns the highest prime that is less than or equal to K.

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.
