true or false: if changes in prices are unpredictable, that is evidence against market hypothesis.

The p-value of a hypothesis test provides information about the strength of evidence against the null hypothesis, from which you are able to ‘reject’ or ‘fail to reject’ conclusions based on a pre-set α. (Please justify your selection) (a) True (b) False
Question 2 (0.5 points) The smaller the P-value, the stronger the evidence against Ho. True False Question 3 (0.5 points) If the P-value is more than the significance level, we reject Ho. O True O False
If the efficient market hypothesis holds, which of the following statements are true? prices do not fluctuate security prices change for no discernible reason future events can be forecast with perfect accuracy prices reflect all available information
of the following statements, two are true and three are false. Which ones are true? A very small p-value is indicative of very strong evidence against the null hypothesis. A very large p-value is indicative of very strong evidence against the null hypothesis. If a null hypotheis is rejected at the 5% significance level, it would also be rejected at the 10% significance level. A very large p-value is indicative of very strong evidence against the alternative hypothesis. A very...
the only reason open market operations work is because prices are sticky. true, false, or uncertain? explain
Determine whether the following statement is true or false. Sample evidence can prove that a null hypothesis is true. Choose the correct answer below. True O False
The P-value for a hypothesis test is given. Determine whether the strength of the evidence against the null hypothesis is weak/none, moderate, strong, or very strong. P = 0.13
True OR False: Ho refers to the 'null hypothesis. True False
Statistics Homework Questions - Help! Please give correct answers and explanations! Thank you! 1. True or False: One advantage of using classical approach over P-values approach in hypothesis testing is that classical approach provide information regarding the strength of the evidence. 2. True or False: P-values are interpreted the same way regardless of the type of hypothesis test being performed. The larger the P-value, the stronger the evidence against the statement in the null hypothesis. 3. True or False: The...
