A biologist exposed a certain type of bacteria to gamma radiation to see how long they would live. He gathered data on the survival time of a number of bacterial cells and organized the data into the histogram below. Use the histogram to construct a frequency table. (The relative frequencies should be in decimal form.) 60+ 50 40 30 10 440 282 Survival Time (in Seconds) 45 124 203 361 519 Survival Time of Bacteria upon Exposure to Gamma Radiation Frequency Survival Time (in Seconds) Relative Frequency 45-124 124-203 203-282 282-361 361-440 440-519 Frequency 20

Recall that a relative frequency histogram is used to graph quantitative data. Classes are chosen to divide the range of values into equal-length subintervals, then plotted along the horizontal axis. A bar is drawn for each class with height equal to the relative frequency for that class. To create a relative frequency histogram, first summarize the following data in a frequency table. 1 N 2 3 4 5 6 7 Class Class Boundaries 8 9 1.3 10 11 14.7 9.0 16.7 4.1 14.9 4.4 2.7 32.3 10.9 9.0 9.0 1.6 18.4 1.0 2.4 2.4 18.0 Since the measurements are all between the values 0 and 33, it will be convenient to choose 11 class intervals of length 3. Using the given data, tally the values within each class interval to determine the frequency of each class, and fill in the following table. 0 to <3 3.5 11.2 18.0 26.7 3.7 3 to 6 6 to 9 9 to 12 12 to < 15 15 to 18 18 to 21 21 to 24 24 to 27 0.2 6.1 13.5 27 to < 30 30 to 33 7.4 8.2 19.2 1 1 2 1 Frequency 10 5 1 4 1 X X 9.4 X 8.7 X 2.0 6.6 3.9 5.9 4.3 3.3 0.2…

Please solve question 5.

A researcher wants to study the academic performance of suburban secondary schools in his county. He decides to measure each school's academic performance by collecting data on the percentage of students passing at least one Advanced Placement (AP) exam. The following table shows each school with the percentage of students passing at least one Advanced Placement (AP) exam.
