The box plot that represents the data is the first option.
<h3>What box plot correctly represents the data?</h3>A box plot is used to study the distribution and level of a set of scores. The box plot consists of two lines and a box. The end of the first whisker represents the minimum number and the end of the second whisker represents the maximum number.
On the box, the first line to the left represents the lower (first) quartile. The next line on the box represents the median. The third line on the box represents the upper (third) quartile.
Minimum value = 30
Maximum value = 57
1st quartile = 1/4 (n + 1)
1/4 x 10 = 2.5th term = 35
Third quartile = 3/4 x (n + 1 )
3/4 x 10 = 7.5 term = 53
Median = 46

Answer:
B.77.4%
Step-by-step explanation:
Mean wage (μ) = $4.50
Standard deviation (σ) = $0.50
For nay given salary X, the z-score is given by:
For X = $3.75, the z-score is:
For X = $5.00, the z-score is:
A z-score of -1.5 corresponds to the 6.68th percentile, while a score of 1 corresponds to the 84.13th percentile. Therefore, the percentage of workers getting paid between $3.75 and $5.00 an hour is:
The answer is alternative B.77.4%
