Solution :
Given that,
Test statistics = -2.598
Test statistics > critical value
The correct decision is :
In a test of hypotheses Ho: M = 456 versus H1:4< 456, the rejection region is...
In a test of hypotheses Ho:f = -28 versus H1:+-28 at the 1% level of significance, when the sample size is 40 and o is unknown the rejection region will be the interval of union of intervals: 0 (-00, -2.576] U (2.576,00) O [2.426, 0) 0 (-00, -2.708] U (2.708,00) 0 (-00, -2.326] U[2.326,00) O 6-00,-2.426]
The rejection region for a 5% level test of H0 : μ ≥ 10 versus H1 : μ < 10 is X¯ < 7.8. Find the rejection region for a 1% level test.
The rejection region for a 5% level test of H0 : μ ≥ 10 versus H1 : μ < 10 is X¯ < 7.8. Find the rejection region for a 1% level test.
(3 points) Suppose that we are to conduct the following hypothesis test. Ho H980 H1: μ > 980 suppose that you also know that σ-: 200, n 100, 1020, and take α-: 0.01 . Draw the sampling distribution, and use it to determine each of the following A. The value of the standardized test statistic: Note: For the next part, your answer should use interval notation. An answer of the form -oo, a is expressed (-infty, a), an answer of...
The rejection region for a 5% level test of Ho: U2 10 versus H4:<10 is X <7.9. Find the rejection region for a 1% level test. The rejection region for a 1% level test is
(a) Find 6,-x2). answer: (b) Determine the rejection region for the test of H. : (H1 - H2) = 2.1 and H,:(H1 - H2) > 2.1 Use a = 0.01. Z > (c) Compute the test statistic. z = The final conclustion is A. We can reject the null hypothesis that (H1-H2) = 2.1 and accept that (H1-H2) > 2.1. OB. There is not sufficient evidence to reject the null hypothesis that (M - M2) = 2.1. (d) Construct a...
help thank you :)
4 pts Question 9 9. In a test of hypotheses H :u= 1873 vs. H:< 1873, the rejection region is the interval (-00, -2.896), the value of the sample mean computed from a sample of size 9 is m = 1792, and the value of the test statistic is t = -2.655. The correct decision and justification are Do not reject H, because the sample is small. Do not reject H, because -2.896 < -2.655. Reject...
please help
