use the display of data to find the mean, median, and mode.
the mean of the data is
(type a whole number or decimal rounded to the nearest tenth as needed.)

Explanation:

Step1: Identify data values and frequencies

From the histogram, values are 10, 11, 12, 13, 14 with frequencies 5, 6, 9, 5, 5 respectively.

Step2: Calculate the sum of the products of values and frequencies

\[ (10\times5)+(11\times6)+(12\times9)+(13\times5)+(14\times5)=50 + 66+108 + 65+70 = 359\]

Step3: Calculate the total frequency

\[5 + 6+9+5+5=30\]

Step4: Calculate the mean

The mean $\bar{x}=\frac{359}{30}\approx12.0$

Answer:

12.0
