Computer Can have command line interface (CLI) and graphical user interface (GUI). Give two advantages and two disadvantages of both type of user interface.

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.

Which statement is true of web-based social media? a.they allow consumers to interact with and update content. b.they cannot be updated easily, as compared to print media. c.they are expensive to produce and maintain, as compared to print and television. d.they can exist independent of the internet.

When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. this can be done by normalizing to values between 0 and 1, or throwing away outliers. for this program, adjust the values by subtracting the smallest value from all the values. the input begins with an integer indicating the number of integers that follow. ex: if the input is 5 30 50 10 70 65, the output is: 20 40 0 60 55
