Name: 38 39 41 45 48 49 49 50 51 51 52 52 53 53 53 54 55 55 57 58 58 59 60 60 62 63 63 64 65 66 68 72 74 74 76 79 82 83 89 90 1. To make a frequency distribution of the data we will create 7 classes. What will be the class width for this distribution? 2. Fill in the following frequency distribution table. Class Limits [1] [4] Relative Class Boundaries Tally Frequency Frequency 3. Create a Frequency Histogram of the data, plotting the frequency on the left vertical axis and the relative frequency on the right vertical axis. [4] 4. State the shape of the distribution (bimodal, normal, skewed left, skewed right, uniform). [1] 5. The average length of a new born baby is 50 cm and the average length of a 1-year-old is 75 cm. Although the data does not include information about age, does this align with the information presented in your histogram? If it does describe how, and if it doesn't describe why it may not.

State the shape of the distribution (bimodal, normal, skewed left, skewed right, uniform). [1] 5. The average length of a new born baby is 50 cm and the average length of a 1-year-old is 75 cm. Although the data does not include information about age, does this align with the information presented in your histogram? If it does describe how, and if it doesn't describe why it may not. [2] 6. a) What percentage of the patients studied have a length between 62 and 85 cm? Is this an example of descriptive or inferential statistics? [2] b) Assume there are currently 380 patients registered at this clinic. If the distribution of infant lengths in the entire clinic is proportional to our sample, what is an appropriate estimate for the total number of infants in the 62 to 85 cm range? Is this and example of descriptive or inferential statistics? [2] 7. Draw the corresponding ogive (cumulative-frequency histogram) for the data. Be sure to label and have a consistent scale on both axes, include units where appropriate, and use a ruler for precision. [4] 26 tv A O W P A >>> 1
