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.
It is advertised that the average braking distance for a small car traveling at 65 miles per hour equals 120 feet. A transportation researcher wants conduct a hypothesis test to determine if the stopping distance is less than 120. What is Type II error in the context of this problem?
Given that the P-value for the hypothesis test is 0.501, what do you conclude? Does it appear that the heights were obtained through measurement or that the subjects reported their heights?
I need help solving for the p-value for this hypothesis test
A golf instructor claims that more than 70% of his students have improved their driving distance by at least 20 yards after viewing and applying the techniques described in his instructional video. If 138 out of 180 viewers say that their driving distance has improved by at least 20 yards, is the instructor's claim valid? Identify the null and alternative hypotheses for this scenario. Is the instructor's claim that "more than 70% of his students have improved their driving distance by at least 20 yards," valid? Your response should include your decision and conclusion in context of the scenario.
Find the quantity (deviance) for testing the hypothesis H0 and the pvalue used
Choose one problem, formulate the null and alternative hypothesis.
State whether you made a Type I error, a Type II error, or the correct conclusion. Children in your community have on average less than 5.2 books at home, and you reject the hypothesis that they have greater than or equal to 5.2 books.
Follow the steps in testing hypothesis to answer the problem:
rejecting a true alternative hypothesis, H1 leads to committing a type II error True or False
The average person spends over 5 years of his or her life on social media. State the null and alternative hypothesis for the scenario using math symbols and words.
My lawn needs mowing , but i do not want to mow if its going to start raining while I'm in the middle of the job. So i am looking at the sky evaluating the weather, using the null hypothesis: "It will rain within the next two hours". In this situation , what would a type I error be?
