Answer:
Step-by-step explanation:
A. add all the data to get the total number of data
n = 23,069
B. to get the first quartile we need to arrange the data into ascending order or from less to greatest.
680 699 720 750 750 775 790 800 800 800 810 820 830 845 855 855 870 875 880 895 900 905 915 925 925 930 940 950 955 965
if the data score are integer then add the two data then divide to 2790 + 800 = 1590 / 2 = 795
Q1 = 795
C. If 7th decile is equal to 900, if we divide each part to 100then the equivalent of 7th decile would be 900 / 100 = 9
