Answer 1

Answer:

$\star\large\mathcal{\underline{\underline{PLEASE \: }}}\large\mathcal\red{\underline{\underline{F}}}\large\mathcal\green{\underline{\underline{OLL}}}\large\mathcal\pink{\underline{\underline{OW \: }}}\large\mathcal\blue{\underline{\underline{ME}}}\star$

Step-by-step explanation:

$here, \: the \: modal \: class \: is \: 13-17$

$lower \: limit \: of \: modal \: class , l = 13$

$class \: size , h = 17-13 = 4$

$F1 = 7$

$Fo = 5$

$F2= 1$

$Mode = l + [\frac{f1-fo}{2f1-fo-f2}]×h$

$=> 13+ [ \frac{7-5}{2(7)-5-1} ]×4$

$=> 13+ [ \frac{2}{14 - 6}]×4$

$=> 13+ \frac{2}{8} ×4$

$= 13$

$therefore, \: mode \: of \: \\ the \: data \: is \: 13.$
