The scatterplot and regression line below show the relationship between how early students turned in an exam (measured by minutes remaining in the exam) and their exam scores. The fitted line has a y-intercept of 87.
What is the best interpretation of this y-intercept?
Choose 1
A. The average score on the exam was approximately 87
B. On average, spending an extra 1 minute on the exam corresponded to an 87-point increase in score.
C. The model indicates that students who spent 5 minutes taking the exam will have an average score of approximately 87 points.
D. The model indicates that students who turned in the exam exactly at the end of the period will have an average score of 87 points.

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
