In hypothesis testing, when the p value is greater than 0.05, it is considered bad practice to accept the null hypothesis as the burden of proof falls on the alternative hypothesis (Choose the ONE best answer): A True B. False C Undefined D. Can't tell need more information

15) Which of the following statements are true? I. If a population parameter is known, there is no reason to run a hypothesis test on that population parameter. II. The P -value can be negative or positive depending upon whether the sample statistic is less than or greater than the claimed value of the population parameter in the null hypothesis. III. The P -value is based on a specific test statistic so it must be chosen before an experiment is...
options are TRUE, FALSE, GREATER THAN, LESS
THAN, EQUAL TO
In the figure, M2 has more mass than My and M1 has more mass than M3. The questions refer to the magnitudes of tensions and weights. M2 T3 MI M3 There is friction between the horizontal plane and M2 (uk # 0). M2 is observed to travel at a constant speed. Assume that the pulleys are frictionless and have negligible mass. Select the appropriate statements to complete the following sentences....
Which of the following statements is true of hypothesis testing? a. A restricted model will always have fewer parameters than its unrestricted model. b. A test of single restriction is also referred to as a joint hypotheses test. c. The t test can be used to test multiple linear restrictions. d. OLS estimates maximize the sum of squared residuals.
Which of the following is true about the distribution of sample means? a.) The mean distribution of sample means is normally less than the population mean. b.) The mean distribution of sample means is more variable than population means. c.) The mean distribution of sample means is normally greater than the population mean. d.) The mean distribution of sample means is the same as the population mean.
Consider a hypothesis testing situation in which the null hypothesis is p = 0.05 and the alternative is p > 0.5. Data is gathered from a random sample and a test statistic of 2.1 is computed. This means the p-value would have to be: A. less than 0.01. B. between 0.01 and 0.05 C. between 0.05 and 0.10 D. greater than 0.10 E. More information is needed in order to determine the p-value.

A stock with a beta greater than 1.0 has lower nondiversifiable risk than a stock with a beta of 1.0. C. A stock with a beta less than zero has no exposure to systematic risk. D. A stock with a beta less than 1.0 has higher nondiversifiable risk than a stock...
