To answer this question, you need to refer to a t-distribution table. Here are the steps:

1. Identify the degrees of freedom (df). The degrees of freedom for a sample is the sample size minus 1. So, for a sample size of 18, df = 18 - 1 = 17.

2. Identify the significance level. The question states that the level of significance is .05.

3. Since this is a one-tailed test (lower tail), you will look up the value in the t-distribution table that corresponds to these parameters.

Looking at the t-distribution table, the t-value that corresponds to a df of 17 and a significance level of .05 for a one-tailed test is -1.740.

So, the correct answer is -1.740.
