Answer 1

Answer #1

Answer is - Reject the Null hypothesis.(option 1)

Explanation: In case of a right tailed t test, we reject the null hypothesis(at the given level of significance) if the value of the test statistic is more than the critical value.

Here, Rebecca found -

Critical value is = 3.64

Value of the test statistic is = 3.95

As we see the value of the test statistic is greater than the critical value, so the null hypothesis is rejected.

The Student's t distribution table gives critical values for the Student's t distribution. Use an appropriate d.f. as the row header. For a right-tailed test, the column header is the value of α found in the one-tail area row. For a left-tailed test, the column header is the value of α found in the one-tail area row, but you must change the sign of the critical value t to −t. For a two-tailed test, the column header is the value...

Suppose that, for a t-test, your computed value for t is +3.28. The critical value of t is +2.048. Explain what this means. Do you reject the null hypothesis or not? Now suppose that you have 28 degrees of freedom and are using a two-tailed (nondirectional) test. Draw a simple figure to illustrate the relationship between the critical and the computed values of t for this result.
