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

A flight travels daily from Pittsburgh to San Antonio. The following list gives the arrival time relative to the scheduled arrival time (in minutes) for a selection of 17 days. (A negative number means that the flight arrived early.) −8, −4, −4, −3, −2, 1, 2, 3, 5, 7, 8, 8, 14, 18, 24, 28, 37 Send data to calculator Frequency 8. 6. 4 2. 5 -10 7 Answer the questions below. 2 0 10 20 30 Arrival time relative to 5:07 (in minutes) 2 (a) For these data, which measures of central tendency take more than one value? Choose all that apply. 1 Mean Median O Mode 40 None of these measures
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…

6. Fill in the missing values in the following table of relative frequency, labelled A- J. Show how you calculate each value, and put your final answer for each value in the table below (e.g., replace "A" with your found value). The method you use can be different from mine, but you must show how you arrive at each value. Hint: go in order. Find A, then B, etc. Tutorial video 3 should be very helpful here. Class Frequency Relative frequency Cumulative relative frequency 1 to 5 300 0.15 0.15 6 to 10 B A 0.20 11 to 15 500 C D 16 to 20 F 0.45 E 21 to 25 H G 0.98 26 to 30 J I 1.00
The infant mortality rate is defined as the number of infant deaths per 1,000 live births. This rate is often used as an indicator of the level of health in a country. The relative frequency histogram below shows the distribution of estimated infant death rates in 2012 for 222 countries. a) Estimate Q1, the median, and Q3 from the histogram. The median is about ______Iper 1,000 live births.Q3 is about ________ per 1,000 live births. I already answered part of this question can you help me figure out the median and Q3. Please see picture for complete question.
