Suppose a 95% confidence interval for the slope of the FICO score on a loan default was (-0.0045, 0.0237). Which of the following is true?

• FICO is not a statistically significant predictor of the probability of a loan default at the 0.05 significance level.
• The probability the slope is between -0.0045 and 0.0237 is 95%.
• The estimate of the slope is 0.0282.
• 95% of the slopes are between -0.0045 and 0.0237.
