Fill in the blank. The critical value tα/2 that corresponds to a % confidence level with 1000 degrees of freedom is 2.33.

The critical value tα/2 that corresponds to a 98% confidence level with 1000 degrees of freedom is 2.33.

Step-by-step explanation:

From the question we are told that

   The critical value is  

From the student's t distribution table the probability of     at a degree of freedom of  1000 is  

Hence the level of significance is mathematically evaluated as

=>    

Generally the confidence level  is mathematically represented as

=>  

=>  

Converting to  percentage

=>    

=>
