Final answer:

To find the t-values for different significance levels and degrees of freedom, you can use a t-table or a calculator with a t-distribution function.

Step-by-step explanation:

(a) t-value: To calculate the t-value, you will need to use a t-table or a calculator with a t-distribution function. For a one-tailed test at the 0.10 significance level, with 14 degrees of freedom, the t-value is 1.345.

(b) t-value: For a one-tailed test at the 0.05 significance level, with 14 degrees of freedom, the t-value is 1.761.

(c) t-value: For a one-tailed test at the 0.05 significance level, with 23 degrees of freedom, the t-value is 1.713.

(d) t-value: For a one-tailed test at the 0.05 significance level, with 60 degrees of freedom, the t-value is 1.671.

(e) t-value: For a one-tailed test at the 0.005 significance level, with 60 degrees of freedom, the t-value is 2.660.
