Pressure values measured by various probes in the test section of a wind tunnel to obtain the freestream velocity have been given in the table below. The researcher who made the measurements concluded that the 7th reading had a value of -2.567 as the "deviation from the mean" and eliminated the data point based on the Chauvenet criterion. However, she later realized that she used the factor "1/n" instead of "1/(n-1)" in the calculation of standard deviation, which was used for data sets with a total number of data points less than 20. Find the value of the 7th reading. n=1 p=246
