Question

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?

Answer #1

this is a left tailed test.

test statistic is:-

**the p value is
:-**

[as this is a left tailed test]

[ using standard normal table]

In a test of the hypothesis
Upper H 0 : mu equals 53H0: μ=53
versus
Upper H Subscript a Baseline : mu greater than 53Ha:
μ>53,
a sample of
n equals 100n=100
observations possessed mean
x overbarxequals=52.452.4
and standard deviation
sequals=3.53.5.
Find and interpret the p-value for this test.

To test Upper H 0: mu equals20 versus Upper H 1: mu less
than20, a simple random sample of size n=17 is obtained from a
population that is known to be normally distributed.
(a) If
x overbar x equals=18.1

compute the test statistic.
t equals=−1.91

c) Approximate the P-value. Choose the correct range for the
P-value below.

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

Test the hypothesis using the classical approach and the?
P-value approach. Upper H 0 : p equals 0.50 versus Upper H 1 : p
less than 0.50 n equals 150 comma x equals 66 comma alpha equals
0.10
?(b) Perform the test using the? P-value approach.
?P-valueequals nothing ?(Round to four decimal places as?
needed.)

(a) Write the claim mathematically and identify
Upper H 0H0
and
Upper H Subscript aHa.
(b) Find the critical value(s) and identify the rejection
region(s). (c) Find the standardized test statistic. (d) Decide
whether to reject or fail to reject the null hypothesis.In a sample
of
10001000
home buyers, you find that
431431
home buyers found their real estate agent through a friend.
At
alphaαequals=0.020.02,
can you reject the claim that
4040%
of home buyers find their real estate agent...

For a one-tail (lower) test for a single population, we do not
reject the null if the test statistic is greater than or equal to
the negative of the critical value.
True or false
