Which of the hypothesis tests listed below is a two-tailed test? Select all correct answers.
Select all that apply:
H0:μ≤8.1, Ha:μ>8.1
H0:μ≥23, Ha:μ<23
H0:μ=5.3, Ha:μ≠5.3
H0:μ=20.2, Ha:μ≠20.2
H0:μ=4.1, Ha:μ≠4.1
A test is said to be two-tailed test if its region of rejection lies in both tails. For such case alternative hypothesis is always of not-equal type.
(A)
H0: μ≤8.1, Ha: μ>8.1 is an one tailed (right tailed) test.
(B)
H0: μ≥23, Ha: μ<23 is an one tailed (left tailed) test.
(C)
H0: μ=5.3, Ha: μ≠5.3 is a two tailed test.
(D)
H0: μ=20.2, Ha: μ≠20.2 is a two tailed test.
(E)
H0: μ=4.1, Ha: μ≠4.1 is a two tailed test.

Which of the hypothesis tests listed below is a left-tailed test? Select all correct answers. Select all that apply: H0:μ≥18, Ha:μ<18 H0:μ≤19.3, Ha:μ>19.3 H0:μ=8, Ha:μ≠8 H0:μ≥11.3, Ha:μ<11.3 H0:μ≥3.7, Ha:μ<3.7
Is there a relationship between confidence intervals and two-tailed hypothesis tests? Let c be the level of confidence used to construct a confidence interval from sample data. Let α be the level of significance for a two-tailed hypothesis test. The following statement applies to hypothesis tests of the mean. For a two-tailed hypothesis test with level of significance α and null hypothesis H0: μ = k, we reject H0 whenever k falls outside the c = 1 − α confidence...
Question A college football coach thought that his players could bench press a mean weight of 275 pounds. It is known that the standard deviation is 55 pounds. A few players thought that the mean weight was less than 275 pounds, so they conducted a hypothesis test. They asked 30 of their teammates for their estimated maximum lift on the bench press exercise and the mean weight was 260 pounds. Which choice shows the correct first three steps to performing...
For the following hypothesis test, determine the null and alternative hypotheses. Also, classify the hypothesis test as two tailed, left tailed, or right tailed The mean local monthly bill for cell phone users in this country was $43.56 in 2001. A hypothesis test is to be performed to determine whether last year's mean local monthly bill for cell phone users has decreased from the 2001 mean of $43.56 Choose the correct null and alternative hypotheses below OA. Ho : μ...
A. Critical Values for Hypothesis Tests (o known) a) For an upper tailed hypothesis test when a = .0197, then 2 = b) For a two-tailed hypothesis test when a = 0.0104, then 2a/2= c) For a lower-tailed hypothesis test when a = 0.0132, then-Za = B. Critical Values for Hypothesis Tests (o unknown) a) For an upper tailed hypothesis test at 27 d.f. and a = .025, then ta = b) For a two-tailed hypothesis test at 58 d.f....
The null and alternative hypotheses are given. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. What parameter is being tested? H0: μ = 9 H1: μ > 9 What type of test is being conducted in this problem? Left-tailed test Right-tailed test Two-tailed test What parameter is being tested? A )POPULATION MEAN B) POPULATION STANDARD DEVIATION C) POPULATION PORPORTION
To identify the correct Z(critical), it is important to determine whether the hypothesis test is one-tailed or two-tailed. The decision between a one- and two-tailed hypothesis is based on the researcher's expectations about the population from which the sample was selected. Many people believe that millennials are having more sex than people during the sexual revolution. You wonder whether the cohort currently in their mid-20s have had more sexual partners than older generations. Assume that the the average number of...
He uses a two-tailed hypothesis test when the null hypothesis is similar to the following: H0: x bar = 100. Select one: True False
For a test of a mean, which of the following is correct? Top of Form H0 is rejected when the calculated p-value is less than the specified level of significance For a left-tailed test, the null hypothesis H0 will be rejected when the test statistic exceeds the critical value . The test statistic value is based on the chosen level of significance. If H0: μ= 5 and H1: μ ≠ 5, then the test can either be a right-tailed test...
A hypothesis test for H0:μ=47 against a two tailed alternative found tc=1.47 where n = 12. What would be the appropriate p-value?
