Question

Find the P-value for the hypothesis test with the standardized test statistic z = 0.52, Right-tailed test, and level of significance = 0.05. Decide whether to reject H0 or fail to reject H0.

Answer #1

P value calculation from standardized z score.

Here P value is **0.3015.**

P value greater than level of significance (α) so, we
**fail to reject Ho (null hypothesis).**

find the p-value for the indicated hypothesis test
with the given standardized test statistic, z. decide whether to
reject H0 for the given level of significance a. right-tailed test
with statistic z=1.47 and a=0.06. p-valuue =

Find the P-value for a left-tailed hypothesis test with a test
statistic of
zequals=negative 1.99−1.99.
Decide whether to reject
Upper H 0H0
if the level of significance is
alphaαequals=0.050.05.

The test statistic of z= "1.43" is obtained when
testing claims that p>0.4 using a significance level of a=0.01,
should we reject H0 or should we fail to reject H0. identify the
hypothesis test as being two-tailed, left-tail, or
right-tailed.
find the p-value

The value obtained for the test statistic, z, in a one-mean
z-test is given. Whether the test is two-tailed, left tailed, or
right-tailed is also specified. For parts (a) and (b), determine
the P-value and decide whether, at the 11% significance level,
the data provide sufficient evidence to reject the null hypothesis
in favor of the alternative hypothesis.
a) The test statistic in a left-tailed test is z=-1.65
the P-value is ___ (round to three decimal places as
needed.)
At...

With H0: p = 0.4, Ha: p < 0.4 , the test statistic is z = –
1.68. Using a 0.05 significance level, the P-value and the
conclusion about null hypothesis are:
ِA) 0.0465; reject H0
B) 0.093; fail to reject H0
C) 0.9535; fail to reject H0
D) 0.0465; fail to reject H0
what is the correct answer?

10. In each part, we have given the value obtained for the test
statistic z in a one-mean z-test. We have also specified whether
the test is two tailed, left tailed, or right tailed. Determine the
P-value in each case and decide whether, at the 5% significance
level, the data provide sufficient evidence to reject the null
hypothesis in favor of the alternative hypothesis. EXPLAIN AND SHOW
ALL WORK
a. z = −1.25; left-tailed test
b. z = 2.36; right-tailed...

The test statistic of z=1.21 is obtained when testing the claim
that p?0.653. a. Identify the hypothesis test as being? two-tailed,
left-tailed, or? right-tailed. b. Find the? P-value. c. Using a
significance level of ?=0.01?, should we reject Upper H 0H0 or
should we fail to reject Upper H 0?

For a right-tailed Z Test, if the test value is 1.87, then for
which significance level will the decision be to not reject
the
null hypothesis?
(a) α = 0.10 (b) α = 0.05 (c) α = 0.01

Assume the computed t-statistic was t0=1.987
Find the t-critical value for a one-tailed test at the 0.05
significance level with 19
degrees of freedom. Is there sufficient evidence to reject the
null hypothesis?
Find the t-critical value for a one-tailed test at the 0.05
significance level with a sample
size of 30. Is there sufficient evidence to reject the null
hypothesis?
Find the t-critical value for a two-tailed test at the 0.05
significance level with 15
degrees of freedom. Is...

Use the given information to find the P-value. Also use a 0.05
significance level and state the conclusion about the null
hypothesis (reject the null hypothesis or fail to reject the null
hypothesis).
(a) The test statistic in a right-tailed test is z = 2.00
(b) The test statistic of z = -1.75 is obtained when testing the
claim that p = 1/3
