True or False
Step by step
Solved in 2 steps with 2 images
- A Bitter Dispute With the publication of Ars Magna, a dispute intensified between Jerome Cardan and another mathematician named Niceolo Fontana, otherwise known as Tartaglia. What was the dispute, and how did it arise? In your opinion, who was at fault? Write a paragraph or two about your findings.If a null hypothesis is rejected at the 0.05 level of significance, it must be rejected at the 0.01 level. True or False?A hypothesis test was conducted to see if a new HIV vaccination reduces the risk of contracting the HIV virus. The implication of a Type II error from the clinical trial is that the vaccination will not be approved when it indeed does reduce the risk of contracting the HIV virus. true false
- While testing a hypothesis, we can do either Type I error, or Type II error, but not both of them. Select one: a. True b. FalseWhen a result is not extreme enough to reject the null hypothesis, explain why it is wrong to conclude that your result supports the null hypothesis.When a researcher rejects a null hypothesis and he should have reject it what can of error has researcher committed?
- if the null hypothesis is not rejected when its false a type II error has been committed. True or FalseSuppose the null hypothesis, H0, is: a patient is not sick. State the Null and Alternative Hypothesis. Which type of error has the greater consequence, Type I or Type II?A Type I error occurs if you reject the null hypothesis when in fact it is true. a.)True b.)False
