Amount of cash (in dollars) in a person's wallet in a small U.S. towrn O Scores on a fairly easy licensing exam for a group of working professionals The histogram for the observations on an unknown quantitative variable called Variable Y is shown here RELATIVE FREQUENCY 0.45 0.40 0.35 0.30 0.25 0.20 0.15 0.10 0.05 0.00 O 0-19 20-39 40-59 60-79 80-99 100-119 The distribution shown in the preceding histogram is Based on the shape of the distribution, which of the following is Variable Y more likely to represent? Scores on a fairly easy licensing exam for a group of working professionals O Amount of cash (in dollars) in a person's wallet in a small U.S. townExplanation / Answer
Consider first histogram diagram,
The tail part of the histogram is on right side therefore the distribution of histograsm is right tailed.
Based on the shape of the distribution the variable x more likely to represent scores on fairly easy licensing exam for a group of working professionals.
Consider second histogram diagram,
The tail part of the histogram is on left side therefore the distribution of histograsm is Left tailed.
Based on the shape of the distribution the variable y more likely to represent scores on fairly easy licensing exam for a group of working professionals.
