Mr. Villalta Math quizzes are normally scored out of 10 marks. Ann got a 3, 7, 9, 10, 8 in her first five quizzes. What is her mean score

The height of 5 athletes are 158 cm, 160 cm, 165 cm, 161 cm, 164 cm. What is the median Height?
Correct Answer
B. 161cm
Explanation
The median height is the middle value when the heights are arranged in ascending order. When we arrange the heights in ascending order, we get 158 cm, 160 cm, 161 cm, 164 cm, 165 cm. The middle value is 161 cm, so the correct answer is 161 cm.

Given the data scores 10, 6, 8, 7, 6, 5, 4 & 3, find the median score:
Correct Answer
B. 6
Explanation
The median is the middle value in a set of data when it is arranged in ascending or descending order. In this case, the data scores are 3, 4, 5, 6, 6, 7, 8, and 10. Since there are 8 scores, the middle value is the 4th score, which is 6. Therefore, the median score is 6.

7.
Use the table provided to find the mean score of the students
Correct Answer
A. 4.4
Explanation
The mean score of the students can be found by adding up all the scores and then dividing the sum by the total number of scores. In this case, the sum of the scores is 4.4 + 4.5 + 5 + 7 = 21.9. Since there are 4 scores, the mean score is 21.9 divided by 4, which equals 5.475. However, since the mean score is typically rounded to one decimal place, the correct answer is 4.4.
8.
Use the table provided to find the median score
Correct Answer
B. 4.5
Explanation
The median score is the middle value when the scores are arranged in ascending order. In this case, the scores are already in ascending order. The middle value is 4.5, as it is the value between 4.4 and 5. Therefore, the median score is 4.5.
9.
Find the median Height of the athletes:
Correct Answer
D. 161
Explanation
The median height of the athletes can be found by arranging the heights in ascending order and then selecting the middle value. In this case, the heights are already arranged in ascending order. Since there is an odd number of heights (4), the middle value is the third height, which is 160. Therefore, the median height of the athletes is 160.
10.
Find the mean height from the table
Correct Answer
C. 161.1
Explanation
The mean height can be found by summing up all the heights and dividing by the total number of heights. In this case, the sum of the heights is 160 + 161.1 + 2577 = 2898.1. Since there are 3 heights, the mean height is 2898.1 divided by 3, which equals 966.03. However, the given answer of 161.1 is incorrect.
