The 98 percent confidence interval (−0.248,−0.134) was constructed to estimate the slope of a regression model for a bivariate data set with 20 values. Alice claims that a sample size of 25 will produce a narrower interval, all other things remaining the same. Desmond claims that a sample size of 15 will produce a narrower interval. Which statement is true about the claims made by Alice and Desmond?     Alice’s claim is correct. A Desmond’s claim is correct. B Both Alice’s claim and Desmond’s claim are correct. C Neither Alice’s claim nor Desmond’s claim is correct. D There is not enough information to determine whether the claims are correct. E
