Answer:
Blue Marlin.
Step-by-step explanation:
In any data set, mean tells about the central tendency of the data. It actually tells the average of the data. On the other hand, standard deviation tells about the spread of the data. It actually tells to what extent the observational values revolve around the mean. Mean is not a good summary statistic of any data since it does not convey the complete information. In order to understand the spread of the data, standard deviation is calculated. The smaller the standard deviation, smaller the spread of the data. It has to be kept in mind that mean has nothing to do with the spread of the data. Smaller the standard deviation, smaller the spread. In this case, lowest standard deviation is of Blue Marlin, which is 1.97. Rest of the standard deviations are larger. This means that Blue Marlin has the smallest spread!!!
Answer:
The decision rule is
Reject the null hypothesis
Step-by-step explanation:
From the question we are told that
The population mean is 
The sample size is n = 160
The sample mean is 
The variance is 
The level of significance is 
The null hypothesis is 
The alternative hypothesis is 
Generally the standard deviation is mathematically represented as
=> 
=> 
Generally the test statistics is mathematically represented as
=> 
=> 
From the z table the area under the normal curve to the left corresponding to 2.53 is
From the value obtained we see that the 
hence
The decision rule is
Reject the null hypothesis
The conclusion is
There is sufficient evidence to conclude that the believe that the valve performs above the specifications is true

Answer:
43091.3 or 43181.81(81 repeated)
Step-by-step explanation:
There are two answers because it depends on the method you use. You can get the second answer by plugging 95 into the equation gram*0.0022=pound or gram=(pound/0.0022). When you insert the 95, you get 43181.81(81 repeated).You can find the first answer by just looking it up on the conversion chart on google.
