(a)
To find: that the mean closer to $2.40, $2.60$ or $2.80.
(a)
Explanation of Solution
Given:
By seeing the histogram, it is observed that, it is approximately symmetric and unimodal. Mean and standard deviation would be the best measure of the centre because of symmetric histogram. Mean is looking at the balancing point of the graph and this graph is close to 2.6 in comparison to 2.4 or 2.8.
(b)
To find: that the standard deviation closer to $0.15, $0.50 or $1.00.
(b)
Explanation of Solution
Given:
Both $0.5 and $1.00 extend the standard deviation outside of the
