The mean and standard deviation of the maximum loads supported by 60 cables are 11.09 tons and 0.73 tons, respectively. Find (a) 95%, (b) 99% confidence limits for the mean of the maximum loads ofall cables produced by the compan

The 95% confidence interval is    

The 99% confidence interval is  

Step-by-step explanation:

From the question we are told that

    The sample  mean is  

     The standard deviation is  

      The sample size is  n =60

From the question we are told the confidence level is  95% , hence the level of significance is    

=>  

Generally from the normal distribution table the critical value  of   is  

Generally the margin of error is mathematically represented as  

=>        

=>      

Generally 95% confidence interval is mathematically represented as  

=>      

=>      

From the question we are told the confidence level is  99% , hence the level of significance is    

=>   is  

Generally the margin of error is mathematically represented as  

=>        

=>      

Generally 95% confidence interval is mathematically represented as  

=>      

=>      

it depends on the weather. because i have flown to seattle when it was pouring down rain and there was one time i flew to ohio when it was snowing hard. whats your situation.
