Question

41.ifthe sample data produce a test statistie (z score) thatisinthe critical region, then which the is the appropriate conclusion for the test? following 42.AType error is defined as 43. In a hypothesis test, an extreme, low-probability value for the score is an indication that 44. Az-score that used for hypothesis testing isalsocalleda 45. If fail to reject the null hypothesis, it means that the data do not provide sufficient you that the treatment an effect. has evidence to say True of false? 46. If a researcher is predictingthata treatment increase then the critical regionfor will scores, a directional testwill be in the right-hand True of false? 47.To be more confident thatatreatment ly does havea effect, a researcher should real use a large value for alpha True of false? used to when the null hypothesis is rejected and 48. In a report, the significarteffectusing an alpha levelofa Jo5 the treatment is shown to have a True of false? 49. Increasing the alpha from 01 to 05 will increasethe power ofa statistical test level True of false?

Explanation / Answer

41)If the value of the test static falls inside the critical region the the null hypothesis is rejected

42)Type I error is defined as the probability of rejecting a true null hypothesis

43) If the probability of the z-score is very small it implies that the null hypothesis is false

44) The z-score is also called as value of the test static
