math help please answer the questions in the 2 pictures

Answer 1

Mean=

$221$

Sum=

$221 \times 5$

$= 1105$

Sum of all observations= 1105

Sum of given observations =

$1105 - 922$

=

$183$

Therefore the answer of first one is 183

No. of observations is 5

Median will be

$\frac{n + 1}{2}$

=

$\frac{5 + 1}{2}$

=

$\frac{6}{2}$

= 3

Therefore the answer of second one is 3
