Question
Give as much information as you can about the P-value of a t test in each of the following situations. (Round your answers to three decimal places.)
(a) Upper-tailed test,
df = 7,
t = 2.0
P-value < 0.005 0.005 < P-value < 0.01 0.01 < P-value < 0.025 0.025 < P-value < 0.05 P-value > 0.05
(b) Upper-tailed test,
n = 14,
t = 3.2
P-value < 0.005 0.005 < P-value < 0.01 0.01 < P-value < 0.025 0.025 < P-value < 0.05 P-value > 0.05
(c) Lower-tailed test,
df = 10,
t = 2.3
P-value < 0.005 0.005 < P-value < 0.01 0.01 < P-value < 0.025 0.025 < P-value < 0.05 P-value > 0.05
(d) Lower-tailed test,
n = 24,
t = 4.2
P-value < 0.005 0.005 < P-value < 0.01 0.01 < P-value < 0.025 0.025 < P-value < 0.05 P-value > 0.05
(e) Two-tailed test,
df = 15,
t = 1.6
P-value < 0.01 0.01 < P-value < 0.02 0.02 < P-value < 0.05 0.05 < P-value < 0.1 P-value > 0.1
(f) Two-tailed test,
n = 16,
t = 1.6
P-value < 0.01 0.01 < P-value < 0.02 0.02 < P-value < 0.05 0.05 < P-value < 0.1 P-value > 0.1
(g) Two-tailed test,
n = 15,
t = 6.1
P-value < 0.01 0.01 < P-value < 0.02 0.02 < P-value < 0.05 0.05 < P-value < 0.1 P-value > 0.1
Explanation / Answer
Answer:
Give as much information as you can about the P-value of a t test in each of the following situations. (Round your answers to three decimal places.)
(a) Upper-tailed test,
df = 7,
t = 2.0
P= 0.0428
0.025 < P-value < 0.05
(b) Upper-tailed test,
n = 14,
t = 3.2
P= 0.0032
P-value < 0.005
(c) Lower-tailed test,
df = 10,
t = 2.3
P= 0.0221
(d) Lower-tailed test,
n = 24,
t = 4.2
P= 0.0002
P-value < 0.005
(e) Two-tailed test,
df = 15,
t = 1.6
P= 0.1304
P-value > 0.1
(f) Two-tailed test,
n = 16,
t = 1.6
P= 0.1292
P-value > 0.1
(g) Two-tailed test,
n = 15,
t = 6.1
P=0.000
P-value < 0.01
