Bags of pretzels are sampled to ensure proper weight. The overall average for the samples is 9 ounces. Each sample contains 25 bags. The standard deviation is estimated to be 3 ounces. The upper control chart limit (for 99.7% confidence) for the average would be ounces.

The value is  

Step-by-step explanation:

From the question we are told that

    The sample mean is  

    The sample size is  n =  25

    The standard deviation is  

Given that the sample size is not large enough i.e  n<  30  we will make use of the student t distribution table  

From the question we are told the confidence level is  99.7% , hence the level of significance is    

=>  

Generally the degree of freedom is  

=>  

=>    

Generally from the student t distribution table the critical value  of   at a degree of freedom of   is  

Generally the margin of error is mathematically represented as  

=>    

=>    

Gnerally the  upper control chart limit  for 99.7% confidence is mathematically represented as

=>        

=>        

the cat is blue because the probability of extension towards the prefix of the diameter of the circle could only mathematically equal to the sum of the roots of the carrots from   your garden.
