Refer to the table to the right summarizing measured amounts of serum cotinine (ng/mL) from a sample of smokers. When nicotine is absorbed by the body, cotinine is produced. Use Cotinine (ng/mL) Frequency percentages to construct the relative frequency distribution corresponding to this frequency distribution. 0-99 12 100-199 16 200-299 18 300-399 3 400-499 1 Complete the relative frequency distribution in the table below. Cotinine (ng/mL) Relative Frequency 0-99 % 100-199 % 200-299 % 300-399 % 400-499 % (Type integers or decimals. Round to one decimal place as needed.)Use the weights of freshmen males in September in the accompanying data set to construct a frequency distribution. Begin with a lower class limit of 50 kg and use a class width of 10 kg. Click the icon to view the weights. Construct the frequency distribution. Weight Frequency 50- (Type integers or decimals. Do not round.)The histogram to the right represents the sepal widths (mm) of a sample of irises. Based on the histogram, what is the number of irises in the sample? Frequency 2.5 2.9 3.3 3.7 4.1 1 4.5 Iris Sepal Width (mm) There are | irises in the sample. (Type a whole number.)Listed below are pulse rates (beats per minute) of females selected in study of body data measurements. Construct the stemplot where each stem is the leftmost digit and each leaf is the rightmost digit. How are the data sorted in the stemplot? 69 70 61 39 59 58 89 97 58 57 47 56 65 92 83 75 38 71 64 73 5 Complete the stemplot below. Write the stems in increasing order
