Question

The one-sample t statistic for testing H0: μ = 10 Ha: μ > 10 from a sample of n = 17 observations has the value t = 2.32.

(a) What are the degrees of freedom for this statistic?

(b) Give the two critical values t* from the t distribution critical values table that bracket

? < t < ?

e) If you have software available, find the exact P-value. (Round your answer to four decimal places.)

Answer 1

Solution: We are given:

(a) What are the degrees of freedom for this statistic?

Answer:

(b) Give the two critical values t* from the t distribution critical values table

Answer: The t critical values at assumed 0.05 significance level are:

Please note the given hypothesis is one-tailed, so if we required to find the t critical value at 0.05 significance level for the given alternative hypothesis, then the critical value is:

e) If you have software available, find the exact P-value. (Round your answer to four decimal places.)

Answer: The right-tailed p-value is:
