follows:

i$)$ Determine the minimum, maximum, mean, mode, median, the fint and third quartiles for the

above sample?

Mean $=$

Mode $=$

Median $=$

$OH=$

$Q3=$

Min$=$

Max$=$

i$)$ Using the results from $($i$)$ above sketch the box$-$and$-$whisker plot for the above sample.

iii$)$ From the boxplot above, what can you conclude about the shape of the sample distribution?

v$)$ Determine the sample mean and the sample standard deviation?

Mean $\stackrel{}{x}=$

Standard deviation $S=$

Determine the limits and percentage of scores that falls within $1$ standard deviations from $t$

mean?

$\stackrel{}{x}+-2S=(longrightarrow)$

Percentage of data $=$
