The following decimal numbers are shown in sign-magnitude form +9286 and +801. convert them to signed-10’s complement form and perform the following operations. note: the msb bit of signed bit in 10’s complement system is 0 while for negative numbers it is 9. also the sum is +10267 which requires 5 digits and a sign.

(+9286) + (-801)

(-9286) + (+801)

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.
