Hey guys, this is for an elementary statistics course. When given a problem, I am having trouble determining which is the data set (X) and which is the weight (W).
For example:
Using the weighted mean, find the average number of grams of fat per ounce of meat or fish that a person would consume over a 5-day period if he ate these:
Meat/Fish
3 oz. fried shrimp
3 oz. veal cutlet
2 oz. roast beef
2.5 oz fried chicken drumbstick
4 oz tuna
Fat (g/oz)
3.33
3.00
2.50
4.40
1.75
Would Meat/Fish be the weight, or would fat (g/oz) be the weight, and why?
