1. $19$ or $24$
2. $24$ or $29$
3. $24$ or $25$

Q. Determine the mode(s) of the following data set.

$23$	$47$	$74$	$54$	$63$
$47$	$91$	$87$	$27$	$74$
$54$	$26$	$84$	$19$	$49$

Q. Amelia was feeding the data points of a data set as follows:

$46$	$25$	$23$	$24$	$6$
$4$	$3$	$21$	$25$	$42$
$25$	$12$	$24$	$23$	$23$

She mistakenly entered the number $42$. Given that the data set is trimodal data, the correct value in place of $42$ is .
