The file P02_56.xlsx contains monthly values of indexes that measure the amount of energy necessary to heat or cool buildings due to outside temperatures. (See the explanation in the Source sheet of the file.) These are reported for each state in the United States and also for several regions, as listed in the Locations sheet, from 1931 to 2000. a. For each of the Heating Degree Days and Cooling Degree Days sheets, create a new Season variable with values "Winter," "Spring," "Summer," and "Fall."
Winter consists of December, January, and February; Spring consists of March, April, and May; Summer consists of June, July, and August; and Fall consists of September, October, and November.
b. Find the mean, median, and standard deviation of Heating Degree Days (HDD), broken down by Season, for the 48 contiguous states location (code 5999). (Ignore the first and last rows for the given location, the ones that contain -9999, the code for missing values.)
Also, create side-by-side box plots of HDD, broken down by season. Comment on the results. Do they go in the direction you would expect? Do the
same for Cooling Degree Days (which has no missing data).
c. Repeat part b for California (code 0499).
d. Repeat part b for the New England group of states (code 5801).

You need to design a circuit that implements the functions in the following table: s0 s1 function0 0 a + 10 1 a – b1 0 a + b1 1 a – 1s0 and s1 are 1-bit control inputs to select the function of the circuit. inputs a and b are 4-bitnumbers in 2s complement form. the output is also a 4-bit number in 2s complement form. you are allowed to use only one ttl 7483 4-bit adder to implement all the functions. but anynumber of other components (except the adder) can be used. hint: design a combinational logic circuit to modify the input b and the “carry input” of theadder depending on the control inputs s0 and s1.important: lab grade will depend on the working of the circuit & will be checked of by your labinstructor.1. is the output valid for the following input combinations: a. s0 = 0, s1 = 0, a = 7, b = 3? b. s0 = 0, s1 = 1, a = 7, b = 3? c. s0 = 1, s1 = 0, a = -4, b = -5? d. s0 = 1, s1 = 1, a = -8, b = 6? 2. what is the range of inputs (for both a and b) that will produce the valid output for all the functions?
