A large company's human resources manager undertakes a research that examines the employment records of 500 employees for absenteeism over the previous year. The data is organised into a frequency distribution by the business researcher conducting the study to assist the human resources manager in analysing the data. This graphs show the frequency distribution. Class interval Frequency 0 – 1 218 2 – 3 207 4 – 5 56 6 – 7 11 8 – 9 8 Determine the class size of the above frequency distribution. For each class of the frequency distribution, determine the class midpoint, the relative frequency and the cumulative frequency.
The following table gives the frequency distribution of the commute distances (in miles) for the population of 50 instructors at a local community college. Compute the Relative Frequencies for the frequency distribution. Fill in the values for the Relative Frequency of each class as decimals, round or keep your decimal solutions to two decimal places (the nearest hundredth) as necessary. Commute Distance (miles) Frequency Relative Frequency 11 - 15 9 ? 16 - 20 14 ? 21 - 25 12 ? 26 - 30 8 ? 31 - 35 5 ? 36 - 40 2 ?
The inner diameters of washers produced by a company can be measured to the nearest thousandth of an inch. If the class marks of a frequency distribution of these diameters are given in inches by 0.345,0.360, 0.375, 0.390, 0.405, 0.420, and 0.435, find a) the class size b) the class limits c) the class boundaries
The goal is to construct a grouped frequency distribution table (GDFT) for this data set. The GDFT should have 10 classes with a “nice” class width. Each class should contain its lower class limit, and the lower class limits should be all multiples of the class width. This problem is to determine what the class should be.
Construct a grouped frequency distribution table (GFDT) for this data set. You want 10 classes with a "nice" class width. A "nice" class width would be a multiple of 5 or 10. Your classes should be labeled using interval notation. Since the data appears to be discrete, use a closed-interval to label each class. Each class should contain its lower class limit, and the lower class limits should all be multiples of the class width.(Note: interval notation for closed intervals will take the following form "[number, number]") 293 297 287 371 301 375 334 370 353 437 335 339 384 352 302 278 356 286 322 304 262 379 300 357 241 315 264 356
Suppose an interval has frequency f . If the class interval with the lowest value is at the lowest row, then _________ is the sum of frequency f and all frequencies below it. greater than cumulative frequency Relative frequency less than cumulative frequency class mark
At a meeting of information systems for regional offices of a national company, a survey was taken to determine the number of employees the officers supervise in the operation of their departments, where X is the number of employees overseen by each information systems officer. Table X_____________________ Frequency 1 _____________________7 2 _____________________5 3 _____________________11 4 _____________________8 5 _____________________9 Referring to the Table above, how many regional officers are represented in the survey results?
A sample of candies have weights that vary from 2.35 grams to 4.75 grams. Use this information to find the upper and lower limits of the first class if you wish to construct a frequency distribution with 12 classes
