C. 16,3Explanation
The correct answer is 16.3. This is the average (mean) score calculated using the data in the table. To find the average, we add up all the scores and divide by the total number of scores. In this case, we add up the products of each score and its corresponding frequency, and then divide by the sum of all the frequencies. The result is 16.3.Rate this question:

The correct answer is 17,1. This is the median age of the data in the table. The median is the middle value when the data is arranged in ascending order. In this case, the data is already arranged in ascending order. There are 100 data points in total, so the middle value is the 50th data point. The 50th data point is 17,1, which is the median age of the data.Rate this question:

The average score of the 40 students in the Mathematics test is 5.1. If one student is not included in the calculation, the average score becomes 5.0. This means that the student who is not included must have a score higher than the average of 5.1 in order to bring the average down to 5.0. Therefore, the student's score must be 9.Rate this question:

B. 7,5Explanation
The median is the middle value of a set of numbers when they are arranged in order. In this case, the numbers given are 7, 8, 5, 6, 9, 7, 10, 9. When these numbers are arranged in order, they become 5, 6, 7, 7, 8, 9, 9, 10. Since there are 8 numbers, the middle value would be the 4th number, which is 7.5. Therefore, the correct answer is 7.5.Rate this question:

Correct Answer
E. 9Explanation
The given data set is 1, 3, 5, 6, 6, 6, 8, 9, 10, 12. To find the third quartile (Q3), we need to determine the value that separates the upper 25% of the data. Since there are 10 data points, the third quartile will be the value at the 75th percentile. When the data is arranged in ascending order, the 75th percentile falls between the 8th and 9th data points. The 8th data point is 9, and the 9th data point is 10. Hence, the third quartile (Q3) is 9.Rate this question:

Correct Answer
B. 1,5Explanation
The given data set is: 2, 4, 3, 2, 6, 5, 5, 5, 4, 8, 7, 6, 8, 4, 3. To find the interquartile range, we first need to find the median of the data set, which is 5. Then, we divide the data set into two halves: the lower half (2, 2, 3, 3, 4) and the upper half (6, 5, 5, 5, 8, 7, 6, 8). The lower quartile (Q1) is the median of the lower half, which is 3, and the upper quartile (Q3) is the median of the upper half, which is 7. The interquartile range (IQR) is the difference between Q3 and Q1, which is 7 - 3 = 4. Therefore, the correct answer is 4.Rate this question:
