Researchers were examining potential associations between (exposure) smoking and (disease) acute myocardial infarction (AMI). They selected 500 adults who were in the hospital for AMIs and matched them with 500 adults also in the hospital for other non-related reasons. The researchers then looked back in medical records to identify if the sample reported smoking in the past. Of the 500 with AMI, 348 were found to be smokers and of the 500 without disease, 115 were found to be smokers.(a) What is the study design?(b) What is the answer to the main calculation of association in this study? (If it is a cohort or experimental study only produce the relative risk or risk ratio.) (c) What is an important issue associated with this study design?

The weight of 46 new patients of a clinic from the year 2018 are recorded and listed below. construct a frequency distribution, using 7 classes. then, draw a histogram, a frequency polygon, and an ogive for the data, using the relative information from the frequency table for each of the graphs. describe the shape of the histogram. data set: 130 192 145 97 100 122 210 132 107 95 210 128 193 208 118 196 130 178 187 240 90 126 98 194 115 212 110 225 187 133 220 218 110 104 201 120 183 124 261 270 108 160 203 210 191 180 1) complete the frequency distribution table below (add as many rows as needed): - class limits - class boundaries - midpoint - frequency - cumulative frequency 2) histogram 3) frequency polygon 4) ogive
