Times of Pennies We gathered 50 pennies and recorded their ages, by figuring AGE = CURRENT YEAR - YEAR ON PENNY.

5 1 9 1 2 20 0 25 0 17 1 4 3 0 25 3 8 28 5 21 19 9 0 5 0 2 1 0 1 19 0 2 0 20 16 22 10 19 36 23 0 1 17 6 0 5 0

a. Prior to drawing any diagrams, attempt to envision what the circulation of penny ages will resemble. Will it be hill formed, symmetric, slanted right, or slanted left?

b. Draw an overall recurrence histogram to depict the dissemination of penny ages. Presently would you depict the state of the dissemination?

Question 20

Blustery Urban communities Are a few urban communities more breezy than others? Does Chicago have the right to be nicknamed The Blustery City"? These information are the normal breeze speeds (in miles each hour) for 55 chose urban communities in the Assembled States:5

a. Build a relative recurrence histogram for the information, (hint:Choose the class limits without including the worth x =35.1 in the scope of qualities.)

b. The worth x = 35.1 was recorded at Mt. Washington, New Hampshire. Does the geology of that city clarify the perception?

c. The normal breeze speed in Chicago is recorded as 10.3 miles each hour. Do you think about this bizarrely breezy?

b. Before you draw a chart, take a gander at the anticipated number of wired and remote families in the table. What patterns do you hope to find in the charts?

c. Utilize a line diagram to depict the anticipated number of wired families for the years 2002 to 2008.

d. Utilize a bar diagram to depict the anticipated number of remote families for the years 2002 to 2008.
