Answer/Step-by-step explanation:
=>Given the no. of hrs a sample of high school Science and English Teachers spend on instructional duties weekly as follows:
Science teachers: 53 56 54 54 55 58 49 61 54 54 52 53 54
English teachers: 52 47 50 46 47 48 49 46 55 44 47
=>Required:
a. Median number of hours worked by Science teachers weekly:
First step to take is to arrange our given data in ascending order as follows =>
49, 52, 53, 53, 54, 54, (54), 54, 54, 55, 56, 58, 61
Next is to find our median which is the the middle value of our data point = 54
b. Median number of hours worked by English teachers weekly:
First, order the data given as follows =>
44, 46, 46, 47, 47, (47), 48, 49, 50, 52, 55
Next is to find the middle data point = 47
C. The group with the highest median number of hours is Science Teachers = 54 hours per week
The difference in the median number of hours worked per week between both groups = 54 - 47 = 7hours
