The dot plot and box plot show different displays of the ages of runners on a track team. Which statements best describe the dot

plot or box plot? Check all that apply. Add the number of dots above each age in the dot plot to find the number of players on the team: 2 + 1 + 3 + 2 + 3 + 2 = 13. Subtract the maximum and minimum values of the box plot to find the number of players on the team: 12 – 7. The median appears clearly on the dot plot at the center of the number line: 9.5. The median appears clearly on the box plot at the line within the box: 10. The dot plot is the only display that can be used to show the variability of the data. The box plot is the only display that can be used to show the variability of the data.

Find the mean of the data summarized in the given frequency distribution. Compare the computed mean to the actual mean of 47.3 m
Harlamova29_29 [7]

Answer:

47.4167

D. The computed mean is close to the actual mean because the difference between the means is less than 5%

Step-by-step explanation:

Given the distribution :

Speed(m/hr) ___ midpoint(x) ___ F ___fx

42 - 45 _______ 43.5 ________21 __ 913.5

46 - 49 _______47.5 _________15 __712.5

50 - 53 _______ 51.5 _________6 __ 309

54 - 57 _______ 55.5 ________ 4 ___ 222

58 - 61 ________59.5 ________ 2 ___ 119

The midpoint, x= sum of lower and upper boundary divided by 2

For instance, (42 + 45) / 2 = 43.5

The computed mean, Σfx / Σf = 2276 / 48 = 47.4167

Actual mean = 47.3 miles

(47.4167 - 47.3) / 47.3 * 100% = 0.24%
