Answer #1

1) df = 20 - 1 = 19

0.861 < 0.874 < 1.066

or, t_{0.2} < 0.874 < t_{0.15}

or, 0.15 < p-value < 0.2

or, 0.1 < p-value < 0.2

2) df = 14

1.076 < 1.271 < 1.345

or, t_{0.15} < 1.271 < t_{0.1}

or, 0.1 < p-value < 0.15

or, 0.1 < p-value < 0.2

3) df = 9

2.262 < 2.386 < 2.821

or, t_{0.025} < 2.386 < t_{0.01}

or, 0.01 < p-value < 0.025

or, 0.01 < p-value < 0.05

4) df = 24

2.797 < 3.104 < 3.467

or, t_{0.005} < 3.104 < t_{0.001}

or, 0.001 < p-value < 0.005

Using a table of critical t-values of the of the t distribution,
find the range of values for the P-value for testing a claim about
the mean body temperature of healthy adults for left-tailed with
n=10 and test statistic t = -2.492
What is the range of values for the P Value?
A) 0.025 < P value < 0.05
B) P Value < 0.005
C) 0.01 < P value < 0.025
D) 0.005 < P value < 0.01

A researcher is conducting a test to determine if the population
mean for group 1 is less than the population mean for group 2. She

Consider the following hypotheses: H0: μ = 61 HA: μ ≠ 61
Approximate the p-value for this test based on the following sample
information. Use Table 2. a. x¯ = 58; s = 10.3; n = 10 0.20 <
p-value < 0.40 0.10 < p-value < 0.20 0.05 < p-value
< 0.10 p-value < 0.05 p-value Picture 0.4 b. x¯ = 64; s =
10.3; n = 10 0.20 < p-value < 0.40 0.10< p-value < 0.20
0.05 < p-value...

Test the hypothesis using the P-value approach. Be sure to
verify the requirements of the test.
Ho: P=0.2 versus H1:p>0.2
N=100, X=30, alpha=0.05
Is NP0(1-P0) greater than or equal to
10?
Use technology to find the P-Value.
_ __ is the null hypothesis, because the P-value is __ _than
a

Test the hypothesis using the P-value approach. Be sure to
verify the requirements of the test.
H0: p=0.2 versus H1: p>0.2
n=200; x=55, α=0.1
Is np0(1−p)0≥10?
Yes
No
Use technology to find the P-value.
P-value=__?__
(Round to three decimal places as needed.)
