Here is ur answer....

scores given :-

19,25,23,20,9,15,10,24,20

Total number of observations = 11

a) mean =

$\frac{sum \: of \: obsrvations }{total \: number \: of \: observations}$

$\implies mean =$

$\frac{19+25+23+20+9+15+10+24+20 + 24}{11} = \frac{209}{11 } = 19</p><p>$

mode = the observation that has highest frequency

so here mode = 20

b)

Number of students who scored above mean marks = 5
