Answer - False
Based on sample information, It is not right we accept or reject the null hypothesis. If the P value is greater, it is not rejected.

What can be concluded by failing to reject the null hypothesis? A. either that the null hypothesis is correct or that the test procedure is not strong enough (i.e. that the sample size is not large enough) to reject the null hypothesis B. that the null hypothesis is correct, therefore the alternative hypothesis should be rejected C. that the function of the alternative hypothesis is incorrect D. that the alternative hypothesis is correct, therefore the null hypothesis should be rejected

3. The following statements are very important. Give them some careful thought and discuss them (a) When we fail to reject the null hypothesis, we do not claim that it is abso- lutely true. We simply claim that at the given level of significance, the data were not sufficient to reject the null hypothesis (b) When we accept the alternate hypothesis, we do not claim that the null hypothesis is absolutely false. We do...

11. If we reject the null hypothesis, what can we conclude, subject to the probability, α? Multiple Choice Reject the null with a probability, α, of making a Type I error. The alternative hypothesis is false. The null hypothesis is true. Both the null hypothesis and the alternative hypothesis are true. 12.
