A)The standard error is too high for this model to be of any predictive use.
B)The 95 percent confidence interval for the coefficient of Femlab is -4.29 to -0.28.
C)Significant correlation exists between Femlab and Cancer at α = .05.
D)The two-tailed p-value for Femlab will be less than .05.

The standard error being high does not necessarily mean the model is not useful for prediction. However, it does suggest there may be some variability in the data and the model may not be as precise. Choices B, C, and D all suggest that there is a significant relationship between Femlab and Cancer, with a negative coefficient indicating that as Femlab increases, Cancer decreases. The 95% confidence interval for the coefficient does not include zero, meaning that it is statistically significant at the α = .05 level. The p-value being less than .05 also supports this conclusion. Therefore, A is the statement that is not true.
