Based on the frequency distribution above, what is the cumulative frequency for the class with lower class

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?

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…

The following is a Frequency Distribution Table for the number of units 40 MPC students are enrolled in for this Summer session.   Class Limits Frequency   0.1 - 1.5        10   1.6 - 3.0         14   3.1 - 4.5         8  4.6 - 6.0         6  6.1 - 7.5         2   What is the Class Width for this frequency distribution?  (fill in the blank below) Class Width =  _____ units
