Homework: Ch. 2 score: 2.61 of 4 pts 2.2.6-T The accompanying table shows the number of students enrolled in the 25 courses being taught this semester at a particular college. Complete parts a through d below EEB Click the icon to view the data table. a) Using the 2* a n rule, construct a frequency distribution for these data. Select the correct choice below and il i the answer boxes to compiete your choice ??. Number of Students 18 to 22 students 23 to 27 students 28 to 32 students 33 to 37 students 38 to 42 students 43 to 47 students Frequency 18 to 23 students 24 to 29 sthudents 30 to 35 students 36 to 41 students b) Using the results from part a, calculate the relative frequencies for each ciass Select the Round to the nearest thousandth as needed) Number of Students S Frequency 18 to 22 students 23to27 students 28 to 32 students 3310 37 students 39 to 42 students Frequency 0.080 Number of StudentsRelative 18 to 23 students 24 to 29 students 0.240 30 to 35 students 36 to 41 students 42 to 47 students 0.240 0.280 0 160

Explanation / Answer

a)

2^k >= n

here n = 25

hence 2^k >= 25

n = 5 is minimum which satisfy the relation

now make 5 different continuous bins and write frequency in that range from data table

you will get

same as option B)

b) just divide by total number to get relative frequency which is 25 here

hence 2/25 = 0.08

6/25 = 0.24 and so on

option A) is correct
