1) The one-sample t statistic for testing

H0: μ = 10

Ha: μ > 10

from a sample of n = 18 observations has the value t = 1.99.

(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.
< t <  

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

2)

The one-sample t statistic for testing

H0: μ = 40

Ha: μ ≠ 40

from a sample of n = 14 observations has the value t = 2.75.

(a) What are the degrees of freedom for t?

(b) Locate the two critical values t* from the Table D that bracket t.

< t <

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