Question

9-5 Consider the following hypotheses:

H₀: μ = 73

H_A: μ ≠ 73

Find the p-value for this test based on the following sample information. (You may find it useful to reference the appropriate table: z table or t table)

a. x¯x¯ = 70; s = 6.9; n = 35

• 0.05  p-value < 0.10
• 0.02  p-value < 0.05
• p-value  0.10

• p-value < 0.01

• 0.01  p-value < 0.02

b. x¯x¯ = 76; s = 6.9; n = 35

• 0.01  p-value < 0.02

• p-value < 0.01

• p-value  0.10
• 0.05  p-value < 0.10
• 0.02  p-value < 0.05

c. x¯x¯ = 70; s = 6.4; n = 19

• 0.02  p-value < 0.05

• p-value < 0.01

• 0.01  p-value < 0.02
• p-value  0.10
• 0.05  p-value < 0.10

d. x¯x¯ = 70; s = 6.4; n = 24

• p-value  0.10

• p-value < 0.01

• 0.01  p-value < 0.02

• 0.05  p-value < 0.10
• 0.02  p-value < 0.05
