rchie is fed up with waiting in line at his local post office, and plans to contact his congresswoman. Archie knows that his complaint will not be well received without data to back it up. So to improve his case, over the next few months Archie records the waiting time for a selection of 27 post office visits made by him and other customers. These waiting times (in minutes) are summarized in the following frequency distribution. Waiting time (in minutes) Frequency 0 to 6 4 7 to 13 9 14 to 20 7 21 to 27 5 28 to 34 2 Based on the frequency distribution, using the midpoint of each data class, estimate the mean waiting time for the data Archie collected. For your intermediate computations, use four or more decimal places, and round your answer to one decimal place.

Mariah Jacobsen is the marketing manager at ABC Electronics, a major consumer electronics supplier in the northwest. Over the last five years, sales of the company's flagship product - the Wizer Anonymizer (the WA) - have been 45000, 45500, 44500, 46000 and 44000 units. This rate of sales is considered average for the product over the last twenty years or so. Ms. Jacobsen believes that the distribution of the WA's sales is normal with a standard deviation of 1500 units. If she were asked to make a forecast of next year's sales to upper management, what is the likelihood that she would be correct if she predicts sales between 43000 and 46000?

Here is a data set: 262 143 161 311 307 150 234 204 174 210 128 273 228 183 184 260 128 243 209 311 190 169 197 179 190 155 188 311 Construct a grouped frequency distribution table (GFDT) for this data set. You want 10 classes with a "nice" class width. Each class contains its lower class limit, and the lower class limits should all be multiples of the class width. Note: the data ranges will be hand graded after the due date for this assignment. If your frequencies are marked correct, you most likely have the classes correct.
