Find the critical value or values for the following values of
the significance level α, sample size n, and alternate hypothesis
H1. The critical value is α = 0.05, n = 7, H1: μ < μ0

Using a table of critical t-values of the of the t distribution,

μ
≠20, you decide on the critical region X bar ≤ 15 and
X bar ≥ 25. Assume X is normally distributed, σ

= 25, and the following four random values
are observed: 9, 20, 15, 11.
a) Would you accept or reject H
0
?
b) What level of
α
is assumed here?
c) What probability value would you report?
d) What would be the appropriate critical region for...

Assume that a hypothesis test will be conducted with null
hypothesis H0: μ > 20.
Find the critical value for a sample with n = 15 and α = 0.05.

Consider the following hypotheses:
H0: μ ≤ 350
HA: μ > 350
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¯ = 363; s = 29; n =
18
( ) p-value < 0.01
( ) p-value 0.10
( ) 0.01 p-value < 0.025
( ) 0.05 p-value < 0.10
( ) 0.025 p-value < 0.05
b. x¯ = 363;...

Find the P – values (5 pts) B.1) With Ha: p < 0.777, the test
statistic is z = -2.45 B.2) With Ha: p > 0.25, the test
statistic is z = 2.40 B.3) With Ha: p ≠ 0.707, the test statistic
is z = 2.15
