According to the data collected and procedure I followed in this lab, please help figure out these answers.

Reflection Questions

1. Summarize your analysis of the data.

2. For the dice portion of the experiment, if the number of dice rolls is increased, what

effect should this have on the mean roll with respect to the base value? Explain.

3. Why are the time measurements not identical in Table B? List at least three reasons.

Explain.

4. How many data values are within one standard deviation of the mean X value? How

does this compare with the performance of a data set that is normally distributed?

5. How many data values are within one standard deviation of the mean time value? How

does this compare with the performance of a data set that is normally distributed?

Build Tables A and B in GS, using B1 for the stainless steel ball and B2 for the nylon ball, to reflect the figures shown below. Note that each table will need 25 rows of data (in addition to the Base Value entry in Table A). Il. Part Two a. Roll the dice, multiply by 10 and enter this result in Table A (in the GS) as the base value. If the result is "tails," enter a plus sign. Interpret the value of your dice roll by using the following rules: 1) all doubles count as zero, (2) 10 and 11 count as 0 and 1, respectively, and (3) all other numbers count as face value. b. Roll the dice again. At the same time, have one of your lab partners "flip a coin" using their phone. If the result of the coin toss is "heads," enter a minus sign in Table A. Enter this value as the ones unit in Table A. c. Repeat step b for all 25 "sign" and "ones unit" entries in Table A. Ill. Part Three a. Place the brick under one end of the board to form an inclined ramp. The board should be positioned so that the side with the two lines is facing up and the blue (start) line is at the top. b. One person should release the stainless-steel ball at the blue line, allowing the ball to roll down the length of the board. Another person should video the ball from before the ball is released to after it runs off the board at the bottom. Use the phone's video feature to determine the difference in time between when the ball crosses the upper Record this time difference in Table B1 (nextBO 140 VOL - 160 4 MIST OFF Is View Document7 . Last Modified: 5m ago v ball is released to after it runs off the board at the bottom. Use the phone's video feature to determine the difference in time between when the ball crosses the upper and when the ball crosses the lower line. Record this time difference in Table B1 (next page). c. Repeat step b to accumulate 25 entries in Table B1. d. Repeat steps b and c for the second ball. 1. Create a new Table C by copying Table A and then complete the "X" entries in Table C by taking the "base value" and adding or subtracting the "ones unit" as indicated by the "sign." 2. Insert Table D below Table C and name the new table "Analysis of Dice Data", and then calculate the average (AVERAGE, look up in your GS) and standard deviation (STDEVP, lookup in your GS) of the "X" values in Table A by using statistical functions built into Google Sheets. 3. Insert Table E below Table D and name the new table "Analysis of Rolling Ball Data", and calculate the average (AVERAGE, look up in your GS) and standard deviation (STDEVP, look up in your GS) of the "time" values in Table B1 by using statistical functions built into Google Sheets. 4. Repeat step 3 for the data in Table B2. 5. When the analysis is completed, be sure each lab partner has a copy of the data and analysis
