Question 1: Refer to accompanying data set and use the 25 home voltage measurements to construct a frequency distribution with five classes. Begin with a lower class limit of 121.7 volts, and use a class width of 0.2 volt. Does the result appear to have a normal distribution? Why or why not?
Voltage Measurements from a Home
| Day | Home (volts) | Day | Home (volts) | Day | Home (volts) | Day | Home (volts) |
|---|---|---|---|---|---|---|---|
| 1 | 121.9 | 8 | 121.9 | 14 | 122.3 | 20 | 122.6 |
| 2 | 122.4 | 9 | 122.2 | 15 | 122.3 | 21 | 122.3 |
| 3 | 122.2 | 10 | 122.4 | 16 | 122.3 | 22 | 122.2 |
| 4 | 122.3 | 11 | 122.2 | 17 | 121.8 | 23 | 121.9 |
| 6 | 122.6 | 12 | 122.1 | 18 | 122.0 | 24 | 121.9 |
| 7 | 122.2 | 13 | 122.2 | 19 | 122.1 | 25 | 122.2 |
Complete the frequency distribution below.
Answer: Fill in the blanks in voltage and frequency section.
| Voltage (volts) | Frequency |
| 121.7- | |

Question 2: The data represents the daily rainfall (in inches) for one month. Construct a frequency distribution beginning with a lower level class limit of 0.00 and use a class width of 0.20. Does the frequency distribution appear to be roughly a normal distribution
| 0.47 | 0 | 0 | 0.23 | 0 | 0.46 | |
| 0 | 0.22 | 0 | 0 | 1.37 | 0 | |
| 0.13 | 0 | 0.01 | 0 | 0.22 | 0 | |
| 0.19 | 0.88 | 0 | 0.01 | 0 | 0.26 | |
| 0 | 0.22 | 0 | 0 | 0.11 | 0 |
Answer: Solve answer for frequency
| Daily Rainfall (in inches) | Frequency |
| 0.00-0.19 | |
| 0.20-0.39 | |
| 0.40-0.59 | |
| 0.60-0.79 | |
| 0.80-0.99 | |
| 1.00-1.19 | |
| 1.20-1.39 | |
