Given:
The data set is
21, 16, 30, 15, 16, 18, 10, 24, 26, 20, 19, 24, 24, 25, 23
10, 15, 16, 16, 18, 19, 20, 21, 23, 24, 24, 24, 25, 26, 30
To find:
The range, average and median for the given data set.
Solution:
Arrange the data set in ascending order.
10, 15, 16, 16, 18, 19, 20, 21, 23, 24, 24, 24, 25, 26, 30
(1)
Range = Maximum value - Minimum value
= 30 - 10
= 20
Therefore, the range of the given data set is 20. All the options are incorrect.
(2)
Therefore, the average score is about 20.73. All the options are incorrect.
(3)
Number of observations = 15, which is odd.
In the arranged data set 8th term is 21.
Therefore, the correct option is b.
Answer:
And if we convert to megahertz we got:
Step-by-step explanation:
For any mechanical wave we have the following general relationship:
where:
v represent the speed of the wave = 299790000 m/s
represent the wavelength for the radio station
f represent the frequency of interest
If we solve for the frequency we got:
And replacing the values we got:
And if we convert to megahertz we got:
