Some of the students in Coach Maness science class kept track of the hours they spent on their science fair projects.Justin spent 16 hours on his project while Johnathan worked on his for 19 hours. Jason worked for 24 hours and Sammie worked on her project 13 hours.How many more hours than the average (mean) of the group did Jason work on his project?
A.5
B.6
C.11
D.18
D
The first three are right.
I think you misread the last question. How many more hours than the average (mean) of the group did Jason work on his project?
Right.
Thank you!
To find the median test score, you need to first arrange the scores in ascending order: 68, 82, 82, 88, 92, 98. The median is the middle value in the set. Since there are 6 scores, the middle value is the average of the 3rd and 4th values, which are both 82. So, the median test score is 82. Therefore, option B is correct.
To find the range of temperatures, you need to subtract the lowest temperature from the highest temperature. In this case, the highest temperature is 77, and the lowest temperature is 28. Therefore, the range is 77 - 28 = 49. So, option D is correct.
To find the median temperature, you need to arrange the temperatures in ascending order: 93, 98, 100, 102, 102, 105. Since there are 6 temperatures, the middle value is the average of the 3rd and 4th values, which are 100 and 102. So, the median temperature is 101. Therefore, option C is correct.
To find the average (mean) hours worked on the science fair projects, you need to sum up the hours worked by each student and divide by the total number of students. In this case, the sum of the hours is 16 + 19 + 24 + 13 = 72. Since there are 4 students, the average is 72/4 = 18 hours. Jason worked for 24 hours, so he worked 24 - 18 = 6 more hours than the average. Therefore, option B is correct.
