COMPLETE THE LAB USING MY CODE AS A HEADSTART
ECET 344 LAB Step 3. Then work out the mean of those squared differences. To work out the mean, add up all the values then divide by how many. First add up all the values from the previous step. We want to add up all the values from 1 to N, where N=6 in our case because there are 6 values: Example (continued): Which means: Sum all values from (X1 47.5)2 to (XN47.5)2 We already calculated (X147.5)2=6.25 etc. in the previous step, so just sum them up: =6.25+56.25+6.25+156.25+ 56.25+156.25=437.5 we need to divide by how many, which is simply done by multiplying by "1/N": Example (continued): Mean of squared differences (POPULATION VARIANCE )=(1/6)437.5=72.916 (Note: this value is called the "Variance") Step 4. Take the square root of that to find the STANDARD DEVIATION: =V(72.91666667)=8.539 Lab Assignment: i Use random number generator to populate the (100 numbers). 2 Make the randos numbers value between [0.50]. i Data collected using the random number generator should tollow nornal distribution (bel1 curve) a. 027 of students score between [0006] points (1.e., 02 studente) b. 14 t of students score between [0T - 12] points (1.e., 14 students) c. 344 of students score between [1324] pothts (1.e., 34 students) d. 34 of atudents score between [25 - 36] points (1.e., 34 students) e. 145 of students score between [3744] points (1.0.,14 students) f. 028 of students score between {4550] points (1.e., 02 student 8 ) store the grades in an ID array. 2rite a complete ci+ program \{using data generated) to calculate: a. The mean. b. Population vartance. e. Standard Deviation.- Output the: - Data generated 50,55,45,60,40,35 Total Numbers 6 Mean 47,5 Population Variance 72.916 standard Deviation B. 539 3integ: The sgrt Eunction is located in the cmath library (Hinelude> ). Use casting where necessary. - Hintar Utilize do... While, while loop or for loops in conjunetion with arrays. 9.
