3. The mode of the data is the value that appears most frequently in the data set. In this case, the mode is 5, as it appears 4 times in the data set. Therefore, the correct answer is D. 5.4. The median of the data is the middle value when the data is arranged in ascending order. In this case, the median is 6.5, as it is the average of the two middle values (6 and 7). Therefore, the correct answer is C. 6.5.5. The mean time of the given data is the average of all the values in the data set. In this case, the mean is 6.78, as the sum of all the values divided by the number of values is 6.78. Therefore, the correct answer is C. 6.78.6. The upper and lower quartiles of the data are the values that divide the data into four equal parts. In this case, the upper quartile is 7 and the lower quartile is 5.5. Therefore, the correct answer is B. 7 & 5.5.7. The quartile deviation of the data is the difference between the upper and lower quartiles divided by 2. In this case, the quartile deviation is 1.5, as the difference between the upper and lower quartiles is 2 and dividing it by 2 gives 1.5. Therefore, the correct answer is D. 1.5.
