Detailed Solution

Concept- To find the median, you first need to sort the data in ascending order. Next, you need to determine the number of values in the specified dataset. If the number of values is odd, the mean is the median. If the number of values is even, then the average of the two middle values should be taken as the median for a particular dataset.
The median is the average value of the dataset when the data is ordered in ascending order. If the data are symmetrically distributed, the median of the data is more frequent.
Arrange the given dates in ascending order 10, 15, 14, 17, 20, 28, 48, 49. Also, the number of values here is 8, which is even. As you know, if your data has an even number of values, the median is the average of the two middle values. If there are 8 numbers, the middle value is 4 and 5 .
Numbers from both sides. From the specified date, you can tell that it is the 4th day and 5 the values are 17 and 20. Therefore, the median is the average of these two values and is given as

Therefore, the median data is 18.5.
Hence, option 1 is correct.
