(N/A) $1$. To find the mean,sum all observations and divide by the total count:
Sum $= 33 + 92 + 55 + 90 + 35 + 77 + 58 + 41 + 80 + 64 + 46 = 671$
Total number of observations $(n) = 11$
Mean $= \frac{671}{11} = 61$
$2$. To find the median,arrange the data in ascending order:
$33, 35, 41, 46, 55, 58, 64, 77, 80, 90, 92$
Since $n = 11$ (odd),the median is the value at the $\frac{n+1}{2}$-th position:
Median $= \frac{11+1}{2} = 6$-th position $= 58$
$3$. To find the mode,identify the value that appears most frequently:
Since every observation appears exactly once,there is no mode.
