Movies and film are actually made up of lots of pictures shown one after another very quickly. Let’s say that our movie is made up of 120 images that make up a ‘moving picture.’ If it would take 10 seconds for one image to download uncompressed, how many seconds would it take to download the entire uncompressed movie? How many minutes is it also?

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.
