Create two problems in testing hypothesis. Determine the given and formulate  the null and alternative hypotheses. Write your answer in your notebook

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%. 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. If instead the population had only 5% dateable individuals, how many times can you expect to swipe right?

Write the null hypotheses. If a = 0.05, should you Reject or Not Reject the null hypothesis. Find x2.

On a state driver’s test, about 45% pass the test on the first try. We want to test if more than 45% pass on the first try. Fill in the correct symbol (=, ≠, ≥, <, ≤, >) for the null and alternative hypotheses

Food inspectors inspect samples of food products to see if they are safe. This can be thought of as a hypothesis test with the following hypotheses. Họ: the food is safe H3: the food is not safe The following is an example of what type of error? The sample suggests that the food is safe, but it actually is not safe. type I O type II O not an error

What are the null and alternative​ hypotheses?     A. H0​: The two​ variables, x and y​, are associated. Ha​: The two​ variables, x and y​, are not associated.   B. H0​: The variable x is dependent upon y. Ha​: The variable y is dependent upon x.   C. H0​: The two​ variables, x and y​, are not associated. Ha​: The two​ variables, x and y​, are associated. The​ P-value is   ​(Round to three decimal places as​ needed.) What is the conclusion of the independence​ test?     A. Do not reject H0. The data provide sufficient evidence of an association.   B. Reject H0. The data provide sufficient evidence of an association.   C. Do not reject H0. The data do not provide sufficient evidence of an association.   D. Reject H0. The data do not provide sufficient evidence of an association.

Do the following for the case below. a. State the null and alternative hypotheses for a hypothesis test. b. Describe the two possible outcomes of the test, using the context of the given situation. The governor claims that the percentage of adults over 24 who have graduated from high school is greater than 75%, the national average. What is the null hypothesis? A. The percentage of adults over 24 who have graduated from high school is 75%. B. The percentage of adults over 24 who have graduated from high school is greater than 75%. C. The national average for the percentage of adults over 24 who have graduated from high school is 75%.

When conducting a hypothesis test, we hope to avoid commiting a type 1 error, which is: 1. Not as bad as committing a type 2 error 2. rejecting a null hypothesis when it is true 3. rejecting the alternate hypothesis when it is true 4. accepting the null hypothesis when the alternate hypothesis is true

Which hypothesis represents the statement of "no change" (or "no affect/difference"),  that we assume to be true?  A.The one hypothesis, H1   B.The null hypothesis, H0   C.The right hypothesis, H0   D.The alternative Hypothesis, H1
