Question

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 , do not reject Ho

c- since the p value is less than a , reject Ho

d- since the p value is greater than a , reject Ho

question 3

What is the p-value if, in a two-tail hypothesis test, Z STAT = -2.01? (ROUND 4 DECIMAL PLACES)

Thanks.

Test the hypothesis using the P-value approach. Be sure to
verify the requirements of the test. H0: p=0.6 versus H1:
p>0.6 n=125; x=85; α=0.1

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?

Test the hypothesis using the P-value approach. Be sure to
verify the requirements of the test. H0: p=0.4 versus H1:
p>0.4 n=250; x=110, α=0.05
Is np01−p0≥10? (no or yes???)
P-value=() (Round to three decimal places as needed.)
(reject or do not reject???) the null hypothesis, because the
P-value is( greater or less????) than α.

Test the hypothesis using the P-value approach. Be sure to
verify the requirements of the test.

In a two tail test, the probability P(ZSTAT ≤
-2.12)=0.017. The true statement (s) is/are:
a. Conclusions reached in b, c, d are true
b. the null hypothesis should not be rejected at
α=0.02
c. the null hypothesis should be rejected at
α=0.04
d. an alternative should be rejected at
α=0.02

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
