9) In 2015, the average math SAT score for students at South Hanover High School was 520. Five years later, a teacher wants to perform a hypothesis test to determine whether the average math SAT score of students at the school has changed since 2015. The hypotheses are: Ho :u=520 Ha :u=520Suppose that the results of the sampling lead to acceptance of the null hypothesis. Classify that conclusion as a Type I Error, a Type II Error, or a correct decision, if in fact the average math SAT score of students at the school is equal to 520.
In Malaysia legal system, a defendant is presumed innocent until proven guilty. Consider a null hypothesis, H0, that a defendant is innocent, and an alternative hypothesis, H1, that the defendant is guilty. A jury has two possible decisions: Convict the defendant (reject the null hypothesis) or do not convict the defendant (do not reject the null hypothesis). Explain the meanings of the risks of committing either a Type I or Type II error in this sample.
In a recent survey, it was stated that Americans watch television on average four hours per day. Assume that σ = 2. Using 40 students as the sample, conduct a hypothesis test to determine if the average for students at your school is lower:
If a hypothesis test were conducted using α=0.01, for which of the following p-values would the null hypothesis be rejected?
According to the Centers of Disease Control, about 22% of American young people between the ages of 12 and 19 are obese.A student claims that the students his local schools are in better shape than the national average, so their proportion of obese students is less than 22%. Which are the appropriate null and alternative hypotheses for this study? H0: p = 22%, H1: p ≠ 22% H0: p ≠ 0, H1: p = 0 H0: p = 22%, H1: p < 22% H0: p = 22%, H1: p > 22% Suppose that the result of the statistical is to reject H0.Which is the proper conclusion? There is not sufficient evidence to conclude that the students at his local schools have a smaller true proportion of obese students. There is sufficient evidence to conclude that the students his local schools have a smaller true proportion of obese students. There is not sufficient evidence to conclude that the students at his local schools have a smaller sample proportion of obese students. There is sufficient evidence to conclude that the…

There is sufficient evidence to support the claim that the students at his local schools have a smaller proportion of obese students. There is not enough information to answer this question. There is not sufficient evidence to support the claim that the students at his local schools have a smaller proportion of obese students.
n 2015, the average math SAT score for students at South Hanover High School was 520. Five years later, a teacher wants to perform a hypothesis test to determine whether the average math SAT score of students at the school has changed since 2015. The hypotheses are: Ho: = 520 Ha: 520 Suppose that the results of the sampling lead to acceptance of the null hypothesis. Classify that conclusion as a Type I Error, a Type II Error, or a correct decision, if in fact the average math SAT score of students at the school is equalnotto 520.
Assess the evidence against the null hypothesis if the P-value of the hypothesis test is 0.062.
When is a researcher at risk of making a type 2 error? whenever H0 is rejected whenever H1 is rejected whenever H0 fails to reject the risk of a type 2 is independent of the decision from a hypothesis test
Massachusetts Institute of Technology grants pirate certificates to those students who successfully complete courses in archery, fencing, sailing, and pistol shooting ("MIT Awards Pirate Certificates to Undergraduates," Boston Globe, March 3, 2012). Sheila claims that those students who go on to earn pirate certificates are able to hit a higher proportion of bull's-eyes during the archery final exam than the course average of 0.15. Specify the null and alternative hypotheses to test her claim.
Based on that information, determine the null and alternative hypotheses. Would this be a one-tailed hypothesis test or a two-tailed test?
