Here is a data set: 299 299 357 359 362 384 408 409 424 443 453 454 467 469 482 491 493 493 494 499 531 551 565 577 580 652 714 731 Construct a frequency distribution table for this data set. Data range Frequency Number of classes: 10 Use a "nice" class width, such as a multiple of 5 or 10. Label classes using interval notation. For example, if the class is 70-79, label it as [70,79]. The lower class limit should be a multiple of the class width. For example, if the class width is 10, the lower class limit should be a number like 30 or 40 (depending on the data).

Assuming you have data for a variable with 2,000 values, using the 2k ≥ n guideline, what is the smallest number of groups that should be used in developing a grouped data frequency distribution?

Generate 1000 random samples of size 10 from a uniform distribution on (10, 20). Create a new variable to find the average of these ten values. Use PROC SGPLOT to look at a histogram (with a normal curve overlaid) of the distribution of the mean. Using SAS.
