I conduct a statistical test of hypotheses and find statistical significance (reject Ho) at level α = 0.01. I may conclude that
A. Ho must also be rejected at α = 0.001.
B. Ho must also be rejected at α = 0.05.
C. Both A and B are true
D. Neither A nor B is true
Option B) is correct.
If P value < .....................then we reject H0

Conduct the following test at the α = 0.05 level of significance by determining (a) the null and alternative hypotheses, (b) the test statistic, and (c) the P-value. Assume that the samples were obtained independently using simple random sampling. Test whether p1≠p2. Sample data are x1=30, n1=254, x2=36, and n2=302. (a) Determine the null and alternative hypotheses. Choose the correct answer below. A. H0: p1=0 versus H1: p1=0 B. H0: p1=p2 versus H1: p1<p2 C. H0: p1=p2 versus H1: p1>p2...
Consider the following hypotheses: He: μ28e The population is normally distributed. A sample produces the following observations: 56 67 62 81 8366 Conduct the test at the 1% level of significance. (You may find lt useful to reference the appropriate table: table or Цеье o. Calculate the value of the test statistic. (Negative value should be Indicated by a minus sign.

A researcher plans to conduct a test of hypotheses at the α = 0.10 significance level. She designs her study to have a power of 0.7 at a particular alternative value of the parameter of interest. The probability that the researcher will commit a Type I error is: 0.7. 0.9. 0.1. equal to the PP‑value and cannot be determined until the data have been collected.
Conduct the following test at the a = 0.01 level of significance by determining (a) the null and alternative hypotheses, (b) the test statistic, and (c) the P-value. Assume that the samples were obtained independently using simple random sampling. Test whether p1 #P2. Sample data are X7 = 30, n = 254, X2 = 36, and n2 = 301. (a) Determine the null and alternative hypotheses. Choose the correct answer below. O A. Ho: P1 = P2 versus H: P1>P2...
n order to conduct a hypothesis test for the population proportion, you sample 480 observations that result in 264 successes. (You may find it useful to reference the appropriate table: z table or t table) Ho: pz 0.60 HA: p0.60 a-1. Calculate the value of the test statistic. (Negative value should be indicated by a minus sign. Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.) Test statistic 2.24 a-2. Find the p-value....
In order to test the following hypotheses at an α level of significance H0: μ ≤ 800 Ha: μ > 800 the null hypothesis will be rejected if a) the test statistic z ≥ zα. b) the test statistic z < zα. c) the test statistic z < −zα. d) the test statistic z = α.
Conduct a test at the a=0.05 level of significance by determining (a) the null and alternative hypotheses, (b) the test statistic, and (c) the P-value. Assume the samples were obtained independently from a large population using simple random sampling. Test whether pa > P2. The sample data are x = 120, n, 251, x2 = 132 and n, -311 (a) Choose the correct null and alternative hypotheses below O A. Ho P1 =Pz versus H, PP2 OB. Ho P, =...
