A car insurance company conducted a survey to find out how many car accidents people hadbeen involved in. They selected a sample of 32 adults between the ages of 30 and 70 andasked each person how many accidents they had been involved in the past ten years.

Task-4. What is normal, positively, and negatively skewed frequency distribution? Accordingly, what shapes of such frequency distributions can a histogram adopt, draw, and label them?
How to construct the frequency distributions? Write down the steps.
A researcher who studies mental health is interested in the length of time (in days) that a patient stays in the hospital after they have presented to emergency having suicidal ideation. The researcher follows the first 30 patients during the month of January and follows them until each one of them is released. Below is the histogram of the data obtained from the 30 patients. 1. What is the shape of this distribution and please construct a frequency table. Given the shape and type of data, which measure of central tendency would you be more likely to report? Why?
How to find the class width of a frequency table?
The data to the right represent the top speed (in kilometers per hour) of all the players (except goaltenders) in a certain soccer league. Construct (a) a relative frequency distribution (b) a frequency histogram, and (c) a relative frequency histogram. What percentage of players had a top speed between 14 and 17.9 km/h? What percentage of players had a top speed less than 13.9 km/h? Speed (km/hr) Number of Players 10–13.9 4 14–17.9 8 18–21.9 18 22–25.9 76 26–29.9 268 30–33.9 177 (a) Construct a relative frequency distribution. Speed (km/hr) Relative Frequency 10–13.9 14–17.9 18–21.9 22–25.9 26-29.9 30–33.9 (Round to four decimal places as needed.)
Among fatal plane crashes that occurred during the past 50 years, 481 were due to pilot error, 99 were due to other human error, 569 were due to weather, 386 were due to mechanical problems, and 256 were due to sabotage. D Construct the relative frequency distribution. What is the most serious threat to aviation safety, and can anything be done about it? Complete the relative frequency distribution below. Relative Cause Frequency % Pilot error Other human error Weather % Mechanical problems % Sabotage (Round to one decimal place as needed.) What is the most serious threat to aviation safety, and can anything be done about it? O A. Mechanical problems are the most serious threat to aviation safety. New planes could be better engineered O B. Weather is the most serious threat to aviation safety. Weather monitoring systems could be improved. O C. Sabotage is the most serious threat to aviation safety. Airport security could be increased. O D. Pilot error is the most serious threat to…
