 If the null hypothesis is accepted, then the research hypothesis is rejected In hypothesis testing, a value is set to assess whether the null hypothesis is accepted or rejected and whether the result is statistically significant A critical value is the score the sample would need to decide against the null hypothesis A probability value isInstead 'don't' reject null hypothesisHere you could say "the null hypothesis was not rejected" or "failed to reject the null hypothesis" because you did not find evidence against the null hypothesis You should NOT say "the null hypothesis was accepted" Your study is not designed to "prove" the null hypothesis (or the alternative hypothesis, for that matter)

 An accepted hypothesis can be rejected later on because of an experiment to test the hypothesis Which causes the hypothesis to change and have a new prediction During a scientific experiment the predicted outcome may change which is okay, but the hypothesisAnswer Hi Shephali, Thanks for the A Anonymity and confidentiality serve important purpose to ensure quality and unbiased output in research Let us see how they are important Anonymity and confidentiality serve as a firewall against biased opinions and favoritism in research Many a timesThe _____ will show whether sample is different from the expected ratios and will tell us whether to accept or reject the null hypothesis 9/16 What fraction of the offspring would you expect to be dominant for both traits in a dihybrid cross?

The significance level of the test is the critical probability in choosing between the null hypothesis and the alternative hypothesis If pvalue is LESS than significance level REJECT the null hypothesis If the pvalue is LARGER than significance level DO NOT REJECT Don't say 'accept a null hypothesis;Thus, researchers hypothesize that there is NO difference between two methods or two groups, etc (NULL);What is hypothesis testing?(cont) The hypothesis we want to test is if H 1 is \likely" true So, there are two possible outcomes Reject H 0 and accept 1 because of su cient evidence in the sample in favor or H 1;

To determine whether to reject the null hypothesis using the tvalue, compare the tvalue to the critical value The critical value is t α/2, n–p1, where α is the significance level, n is the number of observations in your sample, and p is the number of predictors If the absolute value of the tvalue is greater than the critical value, you reject the null hypothesisWhether your hypothesis was supported or not, the experiment added to what you know about your initial question, and there are always more questions to answer The Scientific Method The scientific method is a set of logical steps that helps scientists understand the world It is process of inductive reasoning, or using the observation ofNull Hypothesis Example In testing H H We could use X to do the test a 0 100 100 μ μ = ≠ ⎫ ⎬ ⎭ In this example, we must decide whether H 0 is true or false by determining if X is "close enough" to 100 DIf X is far above or below 100, this will lead us to reject the null DIf the value of X is slightly below or above 100, we
