In a multiple regression output, suppose the quoted 95% confidence interval for a particular regression coefficient extends from 3.76 to 7.12. Which of the following is the best conclusion?

a. The p-value for the coefficient is likely to be large (greater than 0.1, for example).

b. The t-value for the coefficient is likely to be small (less than 1, for example), but it could be positive or negative.

c. The estimated coefficient minus two times its standard error will be positive.

d. None of these choices are necessarily true.
