Problem 33Multiple Choice

Listed below are the heights (in inches) of a group of individuals. Find the mean and median for this set of data.
Do the results support or contradict the belief that the average height of the adults in the group is $66$ inches?
$65$ , $68$ , $66$ , $70$ , $64$ , $69$ , $67$ , $72$

Mean: $65.0$ inches

Median: $62.0$ inches

The median height is significantly lower than $66$ inches, contradicting the common belief

Mean: $62.0$ inches

Median: $61.4$ inches

The mean height is significantly lower than $66$ inches, contradicting the common belief

Mean: $67.6$ inches

Median: $67.5$ inches

The results suggest that the average height of the group is slightly higher than the commonly believed $66$ inches

Mean: $67.0$ inches

Median: $64.5$ inches

The results show that the heights of the individuals in the group are consistently below $66$ inches
