Question

a retired statistician was interested in determining the average cost of a 200000 term life insurance policy for a he randomly sampled 65 subjects what value of alpha was used to create this confidence interval

Answer 1

Answer:

The correct option is the second option

Step-by-step explanation:

From the question we are told that

   The average cost is  $\mu = \ 200 000.00$

   The sample size is  n =  65  

    The upper limit of the 95% confidence interval is  $1050.00

     The lower limit of the 95% confidence interval is $850.00

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

      $\alpha = (100 - 95 ) \%$

=>   $\alpha = 0.05$
