Consider the stem-and-leaf display to the right. a. How many observations were in the original data set? b. In the bottom row of the stem-and-leaf display, identify the stem, the leaves, and the numbers in the original data set represented by this stem and its leaves. c. Re-create all the numbers in the data set and construct a dot plot.

A. 23

b. The bottom row has leaves which are 0, 1, 2 and  the stem is 0. 0.0, 0.1, and 0.2 are the original data.

See attached for the  dot plot

Explanation:

a. To determine the number of observations in the original data set, count the number of leaf in the tale

b. The stem and leaves  is clearly visible on the table , the original data set represented by this stem and its leaves can be gotten by interpreting the stem as the whole number and the individual leaves as it decimal point

c. After getting the original data set represented by this stem and its leaves, the dot plot can easily be plotted.

the benefits of raising bc’s minimum wage to $15 through a

series of pre-announced staged increases far outweigh the likely

costs. claims that such an increase will lead to massive job losses

in low-wage sectors of the economy are not credible.

• an increase to $15 would result in some job losses. however,

the likely impact is less than a 1 per cent reduction in the overall

provincial employment rate, and a 7.6 per cent reduction in the

employment rate for those currently making between $10.25

and $15 per hour.

• the large job loss impacts predicted by some opponents of

minimum wages misrepresent the existing economic research. in

reading and using that research, it is important to recognize that

estimates showing job loss effects of minimum wage increases

apply only to teenagers. estimated effects for young adult and

adult workers range from insignificant to non-existent.

• focusing on teenage workers plays up an inaccurate stereotype

about who earns very low wages in bc and leads to exaggerated

claims about job losses. only 26 per cent of those currently making

between $10.25 and $12 are teenagers, and only 5 per cent

of those making between $12 and $15 are teenagers.
