Question

The data below shows the number of birds spotted by a bird watcher each hour over 10 hours:

7, 11, 14, 3,17, 15, 21, 17, 10, 12
a. Create a cumulative frequency table to represent the data:

Birds Spotted:
Frequency Cumulative:
Frequency:

b. Create a histogram to represent the data:

c. Find the mean, median, mode, and range of the data:

d. Find the minimum, first quartile, third quartile, and maximum of the data:

e. Create a box-and-whisker plot to represent the data:

f. Find the 40th percentile for the data set:

Answer 1

First, we always have to list them from least to greatest: 3,7,10,11,12,14,15,17,17,21.

A. I attached an image of the cumulative frequency table.

B. I wasn't able to make a histogram since I can't find any templates or programs to create it on.

Part C:

Mean: 12.7

Median: 26/2=13

Mode: 17

Range: 21 -3 = 18

Part D:

Minimum: 3

First Quartile: 10

Third Quartile: 17

Maximum: 21

E. I can't a program again, but I can help you over a call if you'd wish.

Part F:

40th Percentile: 0.31
