Ledolter and hogg (see references) report that a manufacturer of metal alloys is concerned about cus- tomer complaints regarding the lack of uniformity in the ’s alloyfilaments. fiftyfil- aments are selected and their melting points determined. the following results were obtained: 320 326 325 318 322 320 329 317 316 331 320 320 317 329 316 308 321 319 322 335 318 313 327 314 329 323 327 323 324 314 308 305 328 330 322 310 324 314 312 318 313 320 324 311 317 325 328 319 310 324
(a) construct a frequency distribution and display the histogram of the data.
(b) calculate the sample mean and sample standard deviation.

What is the x-intercept and y-intercept of the equation 2x+1. 2o

Name and describe the three most important measures of central tendency. choose the correct answer below. a. the mean, sample size, and mode are the most important measures of central tendency. the mean of a data set is the sum of the observations divided by the middle value in its ordered list. the sample size of a data set is the number of observations. the mode of a data set is its highest value in its ordered list. b. the sample size, median, and mode are the most important measures of central tendency. the sample size of a data set is the difference between the highest value and lowest value in its ordered list. the median of a data set is its most frequently occurring value. the mode of a data set is sum of the observations divided by the number of observations. c. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is the product of the observations divided by the number of observations. the median of a data set is the lowest value in its ordered list. the mode of a data set is its least frequently occurring value. d. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is its arithmetic average. the median of a data set is the middle value in its ordered list. the mode of a data set is its most frequently occurring value.
