A Type I error is making a correct decision in a hypothesis test. when a correct null hypothesis is rejected in a hypothesis test. usually not controlled for in a hypothesis test. when a correct alternative hypothesis is rejected in a hypothesis test. both (c) and (d) are true.
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?
Discuss whether the following hypothesis is a good hypothesis (i.e., they are logical, testable, refutable, and positive). Specifically say whether if it is logical, testable, refutable, and positive. If so, why? If not, why not? People who pray regularly are less likely to be injured in an accident
A hypothesis test is conducted in order to determine the average weight of a Kit Kat bar.using the following null and alternative hypotheses: H0: The average weight of a Kit Kat bar is 1.5 ounces. HA: The average weight of a Kit Kat bar is greater than 1.5 ounces. Using complete sentences, explain what both a Type 1 and Type 2 error would be in context of this hypothesis test.
I. Do the following:a. State the null and alternative hypotheses, identify which represents the claim,b. Determine when a type I or type II error occurs for a hypothesis test of the claim.c. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. Explain your reasoning.d. Explain how you should interpret a decision that rejects the null hypothesis.e. Explain how you should interpret a decision that fails to reject the null hypothesis.ProblemAn agricultural cooperative guarantees that the mean shelf life of a certain type of dried fruit is at least 400 days.II. Conduct a hypothesis testA research center claims that less than 50% of senior high school students in public schools in the Philippines have accessed the Internet using cellular phones. In a random sample of 100 SHS students, 39% say they have accessed the Internet using cellular phones. At = 0.01, is there enough evidence to support the researcher’s claim?
Hypothesis testing will consist of four hypothesis tests which you need to complete. While you will not need to show your work or upload any files, each test will require the following: Type of Test: Null Hypothesis: Alternate Hypothesis: SE: Test Statistic: P-value: Decision: Sentence:
When a hypothesis test is being carried out, there are four different situations that can occur depending on the truthfulness of the null hypothesis. Type I error occurs when the following situation happen The null hypothesis is false, but we mistakenly fail to reject it. The null hypothesis is true, but we mistakenly reject it. The null hypothesis is false, and we reject it. The null hypothesis is true, and we fail to reject it.
Rejecting the null hypothesis when it is true is called a _____ error
Perform a hypothesis test at a 5% level of significance to see if the proportion of white individuals who are fatally shot by police is less than the total proportion of white individuals in the United States, which is approximately 60.1% according to the U.S. census bureau.

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).
