John records the dates of a bunch of nickels. Determine the mean date of the nickels. final answer, rounded to 2 decimal places. hint: find the midpoint of each yearly range Date 1990-1999 1980-1989 1970-1979 1960-1969 Frequency 56 42 21 5

The final letter grades earned on a mathematies course are given in the table below. A B C D F W 12 20 10 4 Use a pie chart to represent this data. Write down the work leading to your answer. The last page has a protractor which you may print and use.

3. Create a frequency histogram from the given data frequency table. X 42 48 51 57 63 68 70 79 82 95 s 1 2 1 4 1 4 1 2 1 1

A cheetah can travel 60 km in 30 minutes. What is the average speed of a cheetah? A 2 km/min 30 km/min C 60 km/min 120 km/min 3 4 acer tab h shift alt

The ages (in years) and helghts (in inches) of all pitchers for a beseball team are listed. Find the coefficient of variation for each of the two data sets. Then compare the results. -Click the Icon to view the data sets. CV. %D Round to one decimal place as needed.)

Add the means and divide them by two for each pre-1945 and post-1945 and make an excel bar graph based off this data with error bars on graph

6. Fill in the missing values in the following table of relative frequency, labelled A- J. Show how you calculate each value, and put your final answer for each value in the table below (e.g., replace "A" with your found value). The method you use can be different from mine, but you must show how you arrive at each value. Hint: go in order. Find A, then B, etc. Tutorial video 3 should be very helpful here. Class Frequency Relative frequency Cumulative relative frequency 1 to 5 300 0.15 0.15 6 to 10 B A 0.20 11 to 15 500 C D 16 to 20 F 0.45 E 21 to 25 H G 0.98 26 to 30 J I 1.00

Can you fill the table according to data? Thank you!

Finish times (to the nearest hour) for 10 dogsled teams are shown below. Make a frequency table showing class limits, class boundaries, midpoints, frequency, relative frequencies, and cumulative frequencies. Use three classes. (Round your answer for relative frequency to the nearest hundredth and for midpoint to the nearest tenth.) 308 262 310 268 299 249 257 286 239 278
