Below is a series of statements related to hypothesis testing: which {if any] are true? Cheese all that apply. [: The number of Type 1 errors is determined by the signicance level. C Hypothesis testing should be used to determine whether experimental results can be taken seriously. C, If performing a hypothesis test to test if a drug is mo re effective than an alternative. it is appropriate to use a twotailed test. C If the p-value is low. the null hypothesis is improbable. E Increasing the signicance level {e.g., from 5 percent to 10 percent} will increase Type 2 errors. [: With unknown data. it is easier to achieve a signicant result with a onetailed test than it is with a twotailed test. C The p-value denotes the probability of observing the data (or something mo re extreme} ifthe null hypothesis is correct. C, Condence intervals should be used instead of hypothesis testing because they are more likely to be correct
