Use the magnitudes, rounded to three decimal places, of the 100 earthquakes included in the accompanying data set to construct a frequency distribution. The magnitudes are measured on the Richter scale. Use a class width of 0.5 and begin with a lower the frequency distribution appear to be a normal distribution? Click the icon to view the earthquake magnitudes. Construct the frequency distribution. Magnitude (Richter) 1.0- O 0-0 CH CH Frequency (Type integers or decimals. Do not round.) Does the frequency distribution appear to be a normal distribution? The frequency distribution a normal distribution because the frequencies start low, increase, and then decrease, and are roughly symmetric.

Please do not give solution in image format thanku A car salesman collected data on how many cars were sold at a dealership per day for two weeks. The results were as follows: 6, 7, 4, 3, 1, 2, 6, 6, 6, 7, 4, 4. Make a frequency table and then make a histogram based on that frequency table. What is the shape of the distribution? O Skewed to the right O Skewed to the left O Bimodal O Symmetrical

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 frequency table of grades has five classes (A, B, C, D, F) with frequencies of 5, 13, 16, 4, and 3 o respectively. Using percentages, what are the relative frequencies of the five classes? Complete the table. Grade Frequency Relative frequency. A % 13 % 16 4. F. (Round to two decimal places as needed.) BCD

Finish times (to the nearest hour) for 10 dogsled teams are shown below. Make a frequency table showing class limits, class boundaries, midpoints, frequency, relative frequencies, and cumulative frequencies. Use three classes. (Round your answer for relative frequency to the nearest hundredth and for midpoint to the nearest tenth.) 308 262 310 268 299 249 257 286 239 278
