Determine whether the claim stated below represents the null hypothesis or the alternative hypothesis. If a hypothesis test is performed, how should you interpret a decision that (a) rejects the null hypothesis or (b) fails to reject the null hypothesis? A researcher claims that more than 85% of people had at least one health care visit in the past year. Does the claim represent the null hypothesis or the alternative hypothesis? Since the claim. a statement of equality, it represents the (a) How should you interpret a decision that rejects the null hypothesis?

Dating apps allow us to look a person's profile (or picture) and decide whether we'd like to date them (swipe right) or not (swipe left). Let us treat this like a hypothesis test, with the null hypothesis being that you don't want to date them. Then the swipe right decision is a positive result (rejecting the null) and the swipe left decision is a negative result (not rejecting the null). Suppose you think you're pretty good at deciding who you want to date, and you think that your sensitivity is 80% and your specificity is 66%. 4. If you go through the profiles of 200 people in a population where you expect 25% of the population to be dateable, how many times can you expect to swipe right? Hint: multiply the probability by the number of people to find out the expected number of swipes. 5. If instead the population had only 5% dateable individuals, how many times can you expect to swipe right? 6. Suppose you swipe right on a person from the 25% dateable population and go on a date.…

According to a​ study, approximately​ 60% of US adults believe that they have​ achieved, or are within reach​ of, the​ "American Dream"​ (that is, home ownership and financial​ stability). Now consider a random sample of 400 US adults. What is the probablity that over​ 65% of the sampled adults believe they have reached or are optimistic about reaching the American​ Dream?    NEED ANSWER! No explanattion please

In hypothesis testing, if the test statistic falls in the critical region then we reject the null hypothesis. a. Trueb. False

short answer Ethics:  Which hypothesis, the null or the alternative, is easiest for the math to support?  Knowing that, could someone state their hypothesis so that it is the most likely to be supported?  Should every hypothesis test be done with various wordings of the claim, or is there a structure to the hypotheses that should be followed?

6. A sports analogy for hypothesis tests In recent years, professional sports have incorporated the use of instant replay in order to dispute questionable calls by the referees. For example, in the National Football League (NFL) a head coach is allowed to challenge the referees’ decision twice per game. In order for the referees to reverse their original decision, the instant replay must exhibit clear evidence to the contrary.   Suppose the referees rule that a pass was caught in bounds. The head coach of the opposing team believes the player stepped out of bounds before completely catching the ball, and the coach challenges the referees’ decision.   The referees will review all available evidence (video taken from different camera angles) and make a decision. If there is evidence beyond a reasonable doubt that their original call was incorrect, the play will be called an incomplete pass. However, if there is no clear evidence to contradict the original call, the play will remain…

Rejection of the null hypothesis in the two-sample case imp;ies thatr the a. samples are different on the trait of interest b. populations from which the samples are drawn are different on the trait of interest c. samples are not different on the trait of interest d. populations from which the samples are drawn  are not different on the trait of interest

A survey found that 55% of college professors believe that their online education courses are as good as or superior to courses that use traditional face-to-face instruction. Give the null hypothesis for testing the claim made by the survey. ... Ho: p (Type an integer or a decimal.)

Determine whether the claim stated below represents the null hypothesis or the alternative hypothesis. If a hypothesis test is performed, how should you interpret a decision that (a) rejects the null hypothesis or (b) fails to reject the null hypothesis? A researcher claims that at least 82% of people had at least one health care visit in the past year. Does the claim represent the null hypothesis or the alternative hypothesis? Since the claim does not contain a statement of equality, it represents the hypothesis. (a) How should you interpret a decision that rejects the null hypothesis? There is evidence to V the claim that at least 82% of people had at least one health care visit in the past year. (b) How should you interpret a decision that fails to reject the null hypothesis? There is evidence to V the claim that at least 82% of people had at least one health care visit in the past year.
