A park ranger is studying the age and health of Black Cherry Trees in his park. Part of his study displayed the histogram below. Heights of Black Cherry Trees Frequency ОТ 8 60 65 70 75 80 85 90 Height (feet) Do not worry about the difference between class limits and class boundaries for this example. Just uses classes 60- 65, 65-70, 70-75 etc. 1. Construct a grouped frequency distribution for this data including relative, cumulative, and relative cumulative frequency. 2. Draw a frequency polygon for the data. 3. Draw an ogive for the data. Be sure to label the axis and use appropriate scales. If done using paper and pencil please use a ruler to be accurate.

A researcher is interested in determining if there is a relationship between handedness and penmanship. To study this question, the researcher submitted samples from 100 students to penmanship experts. The samples were rated to be of low, medium or high penmanship quality. The observed frequencies were totaled according to left verses right handedness. Penmanship Handedness low medium high Left 8 29 6 right 9 37 11 Which test is appropriate for this data? Why? Calculate row, column and table totals. State the null and alternative hypothesis. What is the degree of freedom? What is the value of the test statistic? What is the p-value? Are the data statistically significant at the 5% significance level? Do you recognize any flaws in this study
