A semiconductor manufacturer produces devices used as central processing units in personalcomputers. The speed of the devices (in megahertz) is important because it determines the price thatthe manufacturer can charge for the devices. The following table contains measurements on 120devices.680 669 719 699 670 710677 669 700 718 690 681 702 696 692649 675 701 721 683 735 688 763 672681722 663 658 634 720 690679 691 683 705 746 706 649 668717 727683652 720 660 695 701 724 668 698 668 660653 637 660 693 679 682704 652 664 702 661 720 695 670 656723 710 680 684 705 681662 644 683 695 678 674724748 697690656 667 683698672642694 660659 704690724680 739704 695718 660 648703 660 722691 680 685681 715 665 676 665 675 655 659 720 675 697 663This data set: Homework4, has been uploaded with our Homework#4 folder, download and read thisdata to R studio and use it to answer the following questions.a) Calculate the following using R, mean, median, standard deviation and a summary statistic.b) State the meaning of the value of your standard deviation obtained from (a) above.c) Plot stem-and-leaf, dot plot, box plot and histogram.d) Describe the shape of the histogram and state whether the mean is a good measure or not.State a reason for your choice.
