True or False section. When we reject the null hypothesis, we have proven the alternative hypothesis to be true. There are only two possible conclusions in a hypothesis test: reject or fail to reject the alternative hypothesis. A Type I error is made when a true null hypothesis is rejected. A Type II error is made when we fail to reject a true null hypothesis. The level of significance is the probability of making a Type II error. The probability...

1. A Type I error occurs when we: A. reject a true null hypothesis B. reject a false null hypothesis C. do not reject a false null hypothesis D. do not reject a true null hypothesis 2. Whenever the null hypothesis is not rejected, the alternative hypothesis: A. is true B. must be modified C. is rejected D. is not rejected

Is it possible to not reject both the null hypothesis and alternative hypothesis? It kinda sounds impossible by common sense, so I wonder if there's an error in my working, thanks for your help/ In a condition of n=84, (sample mean) = 0.4302, s (sample STDV) = 0.260, d.f.= 83, level of significance 0.05, confidence level 95%, critical value (one tailed) 1.663 I have made a null hypothesis and alternative of H₀: μ (the "estimated" population mean) ≤ 0.453 and...

Remember: if p < .05, then you reject the null hypothesis and accept the alternative hypothesis. If p > .05, then you accept the null hypothesis and reject the alternative hypothesis. In a two-tailed hypothesis test, the null hypothesis means there is no significant difference between the groups, then in the alternative hypothesis you state there is a significant difference between the groups. 1.

True or False A. In hypothesis testing, if you fail to reject the null hypothesis, then you have proven the null hypothesis to be true. B. If you are more concerned about a type I error than a type II error in a hypothesis test, it would be better to use ∝= .01 than ∝= .10. C. If you have complete information for a population (from a census), it would be unnecessary and inappropriate to carry out a hypothesis test...
