1. The number library books read in one semester by a group of 30 second graders is given in the table at the right.  Create a reasonable frequency table for this data set with exactly 5 classes.  Include a relative frequency column in the table.   39 52 59 45 48 48 56 78 63 58 64 43 20 72 39 59 67 66 55 68 27 63 69 67 60 57 48 36 49 56 2. Construct an ordered stem-and-leaf plot for the data given above in #8.  Then, describe the shape of the distribution of the data set (either skewed left or skewed right or symmetric).  (HINT:  to keep appropriate spacing, choose Times New Roman font format for cells used to display the plot and begin each entry with an apostrophe to make the values act as text versus a single number.)

The wages of employees of a small accounting firm are as follows. Draw a bar graph that represents the distribution. $60,000 $14,000 $25,000 $25,000 $16,000 $30,000 $18,000 $20,000 $25,000 $30,000 $18,000 $35,000 $50,000

The Sea Wharf Restaurant would like to determine the best way to allocate a monthly advertising budget of $1,000 between newspaper advertising and radio advertising. Management decided that at least 25% of the budget must be spent on each type of media and that the amount of money spent on local newspaper advertising must be at least two and a half times the amount spent on radio advertising. A marketing consultant developed an index that measures audience exposure per dollar of advertising on a scale from 0 to 100, with higher values implying greater audience exposure. If the value of the index for local newspaper advertising is 50 and the value of the index for spot radio advertising is 80, how should the restaurant allocate its advertising budget to maximize the value of total audience exposure? (a) Formulate a linear programming model that can be used to determine how the restaurant should allocate its advertising budget in order to maximize the value of total audience exposure. If…
