Question

For a two-tail hypothesis test, the test statistic is z = 2.08.
What is the *p*-value?

For a one-tail hypothesis test, the test statistic is z = -2.18.
What is the *p*-value?

Answer #1

**Answer---->>**

For a one-tail (lower) hypothesis test, if the z- or t-test
statistic exceeds the critical value, we do not reject the null
hypothesis.
Select one:
True
False

question 1
what is the p-value if, in a two tail hypothesis test, ZSTAT =
+1.20? ( ROUND TO 4 DECIMAL PLACES)
question 2
If, in a (two-tail) hypothesis test, the p-value is 0.0523 ,
what is your statistical decision if you test the null hypothesis
at the 0.02 level of significance?
Choose the correct answer below?
a- since the p value is less than a , do not reject Ho
b- since the p value is greater than a...

what is the differnce between a one tail z test and a
two tail z test? When should we use one over the other?

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 =

State and support whether the p-value (from the test statistic)
will be applied in a left-tail, right-tail, or two-tail test.

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.

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...

In a one-tail hypothesis test where you reject Upper H 0 only
in the lower tail, what is the p dash value if upper Z subscript
STAT baseline equals negative 1.05?

In
a one tail hypothesis test where you tehect Ho only in the lower
tail what us the critical value of the Tstat test statistic w/ 26
degrees of freedom at the .01 level if significance? (Round to 4
decimal places)

For the given alternate hypothesis (H1) and test statistic (zp
hat), determine the P-value of the test statistic. Use the answer
found in the z-table or round to 4 decimal places.
(a) H1: p < 0.75 The test statistic is zp hat = −1.95.
P-value =
(b) H1: p > 0.35 The test statistic is zp hat = 2.34. P-value
=
(c) H1: p ≠ 0.85 The test statistic is zp hat = 1.85. P-value
=
