The starting salaries of eleven software developers are: (see image below)

Does the 5% level Wilcoxon signed rank test provide significant evidence that the median starting salary is above $50,000?

The Wilcoxon signed-rank test is a non-parametric statistical hypothesis test used when comparing two related samples, matched samples

so Wilcoxon signed-rank test is not applicable for the above problem

But according to the data the median salary is above 50000

since the median value of the given samples is 58000
