Question

If you use a 0.05 level of significance in a two-tail hypothesis test, what decision will you make if ZSTAT=+2.09?

Answer #1

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 decision at a 0.05 level of significance for each of
the following tests? Hint: Find the critical value for each test;
then make a decision. (Round your critical values to two decimal
places.) Part (a) F(3, 27) = 3.00 Fcrit = Retain or reject the null
hypothesis. Part (b) F(5, 17) = 2.61 Fcrit = retain or reject the
null hypothesis Part (c) F(4, 36) = 2.70 Fcrit = retain or reject
the null hypothesis Part (D)...

What is the relationship between the confidence level and the
level of significance of a 2-tail test?
Which Hypothesis Tests use Z distributions?
Which Hypothesis Tests use a Student’s t distribution?

Assume that you plan to use a significance level of α = 0.05 to
test the claim that p1 = p2. Use the given sample sizes and numbers
of successes to find the z test statistic for the hypothesis
test.
In a vote on the Clean Water bill, 44% of the 205 Democrats voted
for the bill while 42% of the 230 Republicans voted for it.

what is the decision rule? Use the 0.05 significance level.
Reject H0 if F>

In a two-tailed hypothesis test of the mean using a 0.05 level
of significance, researchers calculated a p-value of 0.03. What
conclusion can be drawn? The alternative hypothesis should be
rejected because the p-value is so small. The null hypothesis is
true because the p-value is less than the level of significance.
The alternative hypothesis is 3% likely to be true. The null
hypothesis should be rejected because the p-value is less than the
level of significance.
