Question

determine the values of the following quantities: a. t.1,15 b. t.05,15 c. t.05,25 d. t.05,40 e. t.005,40

Answer 1

The values in question represent the threshold t-values for given significance levels and degrees of freedom, commonly used in hypothesis testing. These values would be looked up in a t-distribution table or calculated using statistics software.

Step-by-step explanation:

The values of t with given levels of significance and degrees of freedom are typically found using a t-distribution table or statistical software. These values represent the threshold below which a certain proportion of the t-distribution lies.

a. t.1,15 indicates the t-value for a one-tailed test with 10% significance (or 90% confidence) and 15 degrees of freedom.
b. t.05,15 indicates the t-value for a one-tailed test with 5% significance (or 95% confidence) and 15 degrees of freedom.
c. t.05,25 indicates the t-value for a one-tailed test with 5% significance and 25 degrees of freedom.
d. t.05,40 indicates the t-value for a one-tailed test with 5% significance and 40 degrees of freedom.
e. t.005,40 indicates the t-value for a one-tailed test with 0.5% significance (or 99.5% confidence) and 40 degrees of freedom.

Since exact values are not provided in the question, one would normally look these up in the relevant statistical tables or use statistical software to calculate them.

Answer 2

To determine the values of the quantities t.1,15; t.05,15; t.05,25; t.05,40; t.005,40, we need more information.

Step-by-step explanation:

To determine the values of the quantities t.1,15; t.05,15; t.05,25; t.05,40; t.005,40, we need more information. It seems like these quantities are related to some equations or formulas, but the given information is not enough to solve for them.
