According to Wine-Searcher, wine critics generally use a wine-scoring scale to communicate their opinions on the relative quality of wines. Wine scores range from 0 to 100, with a score of 95-100 indicating a great wine, 90-94 indicating an outstanding wine, 85-89 indicating a very good wine, 80 - 84 indicating a good wine, 75-79 indicating a mediocre wine, and below 75 indicating that the wine is not recommended. Random ratings of a pinot noir recently produced by a newly established vineyard in 2018 follow: Excel File: 91 77 a. Develop a point estimate of mean wine score for this pinot noir (to 2 decimals). 87 60 9.5574 86 80 82 79 72 83 80.78 b. Develop a point estimate of the standard deviation for wine scores received by this pinot noir (to 4 decimals). 91 96
