Textbook Question
Chapter 17, Problem 78E
Thirsty? Researchers randomly assigned participants either a tall, thin “highball” glass or a short, wide “tumbler,” each of which held 355 ml. Participants were asked to pour a shot (1.5 oz = 44.3 ml) into their glass. Did the shape of the glass make a difference in how much liquid they poured? Here are the summaries:
Highball | Tumbler | ||
n | 99 | n | 99 |
ӯ | 42.2 ml | ӯ | 60.9 ml |
s | 16.2 ml | s | 17.9 ml |
Test an appropriate hypothesis and state your conclusions. For assumptions and conditions that you cannot test, you may assume that they are sufficiently satisfied to proceed.

- Skrifleg dæmi The consumer association decided to conduct a study comparing three different types of baking powder (A, B and C) in order to check if there was a difference in their effectiveness. The study was carried out in such a way that six cakes were baked with each type of baking powder. The volume of the cakes was measured and the following sizes were also calculated SST = 2039.72, MSg = 82.40 a) Fill in the following square sum table (you should write six numbers in the table): analysis of degress of variance freedom ave week sums SSTR = MSTR = SSE = MSE = 82.40 SST = 2039.72 b) Check with an appropriate hypothesis test whether there is a difference in the average volume of the cake depending on the type of baking powder used.
