I am trying to draw this picture:

I have tried a lot of things, like defining this

newcommandirregularcircle[2]{

pgfextra {pgfmathsetmacrolen{(#1)+rand*(#2)}}

+(0:len pt)

foreach a in {10,20,...,120}{

  pgfextra {pgfmathsetmacrolen{(#1)+rand*(#2)}}

  -- +(a:len pt)

} -- cycle

}

But it don't give a figure that can be between the x-axis and the circle, and I don't know how to do this. Thanks.

Usually one builds up a random list and plots a smooth curve through it.

documentclass[tikz,border=3.14mm]{standalone}

usetikzlibrary{patterns}

begin{document}

begin{tikzpicture}

 pgfmathsetseed{9}

 foreach X in {0,...,12}

 {ifnumX=0

   pgfmathsetmacro{myradius}{2}

   xdefmyLst{myradius}

  else

   pgfmathsetmacro{myradius}{{myLst}[X-1]+0.5*(rnd-0.5)}

   xdefmyLst{myLst,myradius}

  fi}

 draw[pattern=north east lines] (2,0) -- 

 plot[smooth,variable=x,samples at={0,...,11}] 

  ([xshift=2cm]-x*10:{{myLst}[x]}) -- (-60:2) arc(-60:0:2);

 draw (120:2) arc (120:-120:2);

 draw[-latex] (0,0) -- (5,0);

 draw[dashed] (2,0) -- (2,-pi);

 draw (2,0) -- ++ (-120:pi);

 draw[-latex] (2,0) + (-120:2.7) arc(-120:-90:2.7) node[midway,below]{$mu$};

 draw[-latex] (2,0) -- ++ (-45:1) node[pos=1.2]{$z$};

end{tikzpicture}
