What is the percentile rank for a score of 4 in the frequency distribution table below? X__f 6    4 5     5 4      1 3      3 2       6 1        1

The histogram has a longer tail/appears roughly the same/has a longer right tail so the distribution of the data is not skewed/skewed to the left/ skewed to the right

For the data set (−2,−3),(1,1),(5,6),(9,6),(12,11), find interval estimates (at a 92.2% significance level) for single values and for the mean value of y corresponding to x=4 Note: For each part below, your answer should use interval notation. Interval Estimate for Single Value =  Interval Estimate for Mean Value =

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. Take pictures of your work and upload them here.
