Median is the central tendency of the data and always exists in the middle of the data set.
<h3>What is the median?</h3>
The Median is the middlemost value of the numbers arranged in the ascending orders. Median is the central tendency of the data and always exists in the middle of the data set.
The process of finding the median if the number of data points is even is as follows:
- Put the numbers or the data points in the order(increasing or decreasing i.e. ascending or descending order)
- Next cross of the high/ low pairs
- Add the leftover numbers
- and divide the number( as obtained in the above step by 2)
( if the number of data pints were even then we just need to arrange the numbers and cross the high/low pair and only one data point will be left which acts as the Median of the data set)

Answer: The null and the alternative hypotheses are given below:
Under null hypothesis, the test statistic is:
Now we have to find the left tailed critical value at 0.01 significance level using the standard normal table.
The critical value is:
Since the test statistic is -0.26 lies in acceptance region because the critical region is beyond -2.33, therefore, we fail to reject the null hypothesis.
