Question

how might this standard appear on a test? 2) a survey group conducted a study to determine if there is an association between the age of a person and the average number of emojis used per text. the survey results are below. age and emojis used per text

age	15	28	36	10	62	47	23	14	16	20	40	33	50	42	30	12	30	68	70	54
average number of emojis used per text	10	8	5	9	1	1	7	9	8	6	3	4	2	2	6	10	3	6	0	1

a) create a scatter plot using the data in the table. b) what type of association do the two variables seem to have? no association positive linear association negative linear association non - linear association c) does there appear to be an outlier? yes no if yes, where? ____________ d) based on the data, what can you say about age and the number of emojis used per text?

Explanation:

Step1: Create scatter - plot

On the x - axis, plot the age values and on the y - axis, plot the average number of emojis used per text values from the table. Each pair of age and emoji - count is a data point on the scatter - plot. (Note: As this is text - based, we can't actually draw the scatter - plot here, but the process is as described).

Step2: Determine association

As the age increases, the average number of emojis used per text generally decreases. So, there is a negative linear association.

Step3: Check for outlier

Visually inspecting the data points on the scatter - plot (if drawn), we can see that the point corresponding to age = 15 and average number of emojis = 10 might be an outlier as it seems far from the general trend.

Step4: Interpret data

Based on the data, there is a negative linear relationship between age and the average number of emojis used per text. Younger people tend to use more emojis per text compared to older people.

Answer:

a) (Can't be shown in text - based format. Process described above)
b) NEGATIVE LINEAR ASSOCIATION
c) YES, at age = 15, average number of emojis = 10
d) There is a negative linear relationship between age and the average number of emojis used per text. Younger people tend to use more emojis per text.
