Read the t statistic from the t distribution table and choose the correct answer. For a one-tailed test (upper tail) with a sample size of 16 and at the .10 level, t =
Homework Answers
Solution:
We are given
Test is upper tailed test.
Sample size = n = 16
df = n – 1 = 16 – 1 = 15
α = 0.10
So, required critical t value by using t-table is given as below:
t = 1.340606
Answer: t = 1.34

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...

The t statistic, the t distribution, and sample size
The average duration of labor from the first contraction to the birth of the baby in women over 35 who have not previously given birth and who did not use any pharmaceuticals is 16 hours. Suppose you have a sample of 35 women who exercise daily, and who have an average duration of labor of 16.9 hours and a sample variance of 39.7 hours. You want to test the hypothesis that...

To identify the correct Z(critical), it is important to determine whether the hypothesis test is one-tailed or two-tailed. The decision between a one- and two-tailed hypothesis is based on the researcher's expectations about the population from which the sample was selected. Many people believe that millennials are having more sex than people during the sexual revolution. You wonder whether the cohort currently in their mid-20s have had more sexual partners than older generations. Assume that the the average number of...
