standard deviation of 1.0. I am going to order 5000 garnet wedding rings from my reliable Siberian source. They will manufacture ring size from 4.0‚ 4.5‚ 5.0‚ 5.5‚ 6.0‚ 6.5‚ 7.0‚ 7.5‚ 8.0‚ 8.5‚ 9.0‚ and 9.5. How many wedding rings should I order for each of the ring size if I order 5000 rings altogether? (Note: It is natural to assume that if your ring size falls between two of the above standard manufacturing size‚ you will take the bigger of the two.) 2. (8 points) According to a study by

The sensitive period is sometimes regarded as critical‚ implying that‚ once it is past‚ that specific skill can no longer be learnt. The idea that human language is normally acquired during a critical period was proposed by Lenneberg with the Critical Period Hypothesis (CPH). Considering

Question- Does adding peat moss to sand affect its ability to hold water? Hypothesis- If I add peat to sand‚ then the peat moss will hold most of the water because the peat moss can hold large amounts of water. Variables- Manipulated Variable- adding peat moss to sand Responding Variable- peat moss can hold most of the water amount Levels- 100% sand‚ 60% sand/40% peat moss‚ 40% sand/60% peat moss‚ 80% sand/ 20% peat moss Trials- 5 Constants- same amount of water‚ same kind of containers‚ same sand

Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. 3. What would your experimental approach be to test this hypothesis? 4. What are the independent and dependent variables? 5. What is your control? 6. What type of graph is appropriate for this data set?

significant difference in the NP solution and the creek water solution. Although we found that the duckweed grows faster in the NP solution‚ rather than the creek water they do indeed have relatively the same mean. Overall our results supports our hypothesis. This also makes us question what kinds of factors are affecting the creek water to kill off the duckweed. Duckweed also is known to stop the growth of algae‚ but in our experiment we ended up having algae grow in some of the wells filled with creek

The hypothesis for the Oil Absorbency Lab was rejected. My hypothesis was that if a person puts a sponge in materials “crude oil”‚ then it will absorb the most amount of oil. The data collected from this experiment rejected the hypothesis because it stated that the sponge would absorb the most oil‚ but the sponge did not absorb more oil than the rag. The rag and sponge’s ranges were for the first trial was 53.0g‚ the second trial was 51.0g‚ and the third trial was 46.0g and the rag. The rag and
