Question

For the following hypothesis​ test: With n​15, s​7.5, and ​62.2, state the conclusion. A. Because the computed value of t0.878 is not less than 2.1448 and not greater than​ 2.1448, do not reject the null hypothesis. B. Because the computed value of t0.878 is not less than 2.1448 and not greater than​ 2.1448, reject the null hypothesis. C. Because the computed value of t1.312 is not less than 2.1448 and not greater than​ 2.1448, do not reject the null hypothesis. D. Because the computed value of t1.312 is not less than 2.1448 and not greater than​ 2.1448, reject the null hypothesis.

Answer 1

A. because the computed value of t 0.878 is not less than 2.1448 and not greater than 2.1448, do not reject the null hypothesis.

Explanation:

The null hypothesis is accepted or rejected on the basis of t value. If the t value of a computed value is greater than the critical value we reject the null hypothesis. If the absolute value of t value is less than the critical value we fail to reject the null hypothesis.
