Problem 1: A hypothesis test is done in which the alternative hypothesis is that more than 10% of a population is left-handed. The p-value for the test is calculated to be 0.025, and the level of significance is 5%. Which statement is correct? We cannot conclude that more than 25% of the population is left-handed. We can conclude that more than 10% of the population is left-handed We cannot conclude that more than 10% of the population is left-handed We can conclude that more than 25% of the population is left-handed
Problem 2: If the word significant is used to describe a result in a new article reporting on a it may be significant in the statistical sense but not in the everyday sense. the sample size must have been very small the population statistic for the test must have been very small the p-value for the test must have been very large.
