Hello, I have a task and I don't know how to go about making some of them
1.For the 10-element vector of random numbers calculate the mean and then MSE (Mean Squared Errors) and SSE (Sum of Squared Errors) - if I can ask for help, how can I execute it with what commands?
10 - element vector:
2.To what value do qualitative indicators converge with the increase of random samples?

Use mean() to calculate the mean. Then MSE is the "mean squared error": mean((b - mean(b)) .^2).
There is no magic. Simply try it. If you get a specific problem, post your code and explain the problem here.
For your 2nd question: Use a variable n instead of a fixed size of 10. Then increase n to find out by experiments, to examine the results.
