We have for given data,          
              
Sample mean =60.6      
Sample standard deviation =8.75  
Sample size =10      
Level of significance=1-0.95=0.05      
Degree of freedom =9      
              
t critical value is (by using t table)=2.262      
              
Confidence interval formula is               


=(54.341, 66.859)          
              
              
Lower confidence limit=   54.341  
              
Upper confidence limit=   66.859

2. In the Gulf of Maine, 7different species (two types of mussels, barnacles, and four types of seaweed) colonize the rocky intertidal zone between the low-and high-tide marks. These species are sessile, meaning they attach to the rock, so they are in competition with each other for space. Within any square meter, there are always 4 and only 4 species. How many possible ways can a square meter be inhabited? Within any square meter, the spaces occupied by the species...

We are trying to maximise the lifetime of a particular engine by testing two different types of maintenance schedule. We test Schedule A on 40 engines which leads to an average lifetime of 13.2 years with a standard deviation of 3.1. We test Schedule B on another 40 engines which leads to an average lifetime of 10.4 years with a standard deviation of 2.1. The 98.5% confidence interval for the difference in the lifetimes is given by: A. [1.64,3.96] B....

The two claws of the lobster (Homarus americanus) are identical in the juvenile stages. By adulthood, however, the two claws normally have differentiated into a stout claw called a “crusher” and a slender claw called a “cutter”. In a study of the differentiation process, 26 juvenile animals were reared in smooth plastic trays and 18 were reared in trays containing oyster chips (which they could use to exercise their claws). Another 23 animals were reared in trays containing only one...
