a is .05 and N-25, the probability of rejecting the null hypothesis if the mull hypothesis is true is: a. .os b..95 c. 05/25 - 01 d..95/25 = .19 e. insufficient information to answer as the popu 4. The sampling distribution of the mean always has the same distribution of the raw scores. a. mean b. standard deviation c. skew d. a and b e. all of the above S. If the sample size on which a standard deviation is...
The larger the p-value, the higher the chance of rejecting the null hypothesis. O True O False
The higher the alpha level, a. the lower the probability of rejecting the null hypothesis. b. the greater the probability of rejecting the null hypothesis. c. the larger the sample size has to be to reject the null hypothesis. d. the more desirable the two-tailed test. When solving the formula for finding Z(obtained) with sample proportions in the two-sample case, we must first estimate a. the population proportion. b. the critical region. c. the ratio of the sample proportions. d....
not rejecting the null hypothesis means that the assigned value under the null is the true population value. true or false

The smaller the p value _____. a. The more evidence we should reject the null hypothesis b. The less evidence we should reject the null hypothesis c. The more likely it is that the results are not significant d. Has no relationship with significance 23. Hospital autopsies include which of the...
In hypothesis testing, which of the following results in a type I error? Rejecting a true null hypothesis Rejecting a true alternative hypothesis Rejecting a false null hypothesis Rejecting a false alternative hypothesis
Explain what a P-value is. What is the criterion for rejecting the null hypothesis using the P-value approach? Explain what a P-value is. Choose the correct answer below. OA. A P-value is the probability of observing a sample statistic as extreme or more extreme than the one observed under the assumption that the statement in the null hypothesis is true B. A P-value is the number of standard deviations that the observed proportion is from the proportion stated in the...
Given f(.) is some probability density function, fill in the blank with 1) (10 pts total) Given f is some probability density function, fill in the blank with the common name, value or function name for each of the following equations. Note that fo is not necessarily the same from one equation to the next. In some cases there may be more than one correct answer, e.g., "E(X)" or "ux", in which case you only have to provide one of...
