Answer 1

okay so youll have to put the number from smallest to largest so itll be like this

33, 38, 41, 44, 52, 55, 62, 67

now youll have to find the median which is the middle number so in this case the median is between 44 and 52 so youll have to do 44+52/2 to get the median and so your median is

median=48

after finding the median you can easily find Q1. so what you do is look at the first number which is 33, then you look at the median of the whole thing which s 48. so now tou have to find the median (midle number) from 33 to 48 which is your Q1. so your Q1 is between 38 and 41 so we use the method of finding the median, so you do 38+41/2 which = 39.5

Q1= 39.5
