In 2016, 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 2016. The hypotheses are: Ho : = 520 Ha : ≠ 520 Suppose that the results of the sampling lead to rejection 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 not equal to 520

In 2015, the average math SAT score for students at South Hanover High School was 520. Five yearslater, a teacher wants to perform a hypothesis test to determine whether the average math SAT score ofstudents at the school has changed since 2015. The hypotheses are:Ho :  = 520Ha :   520Suppose that the results of the sampling lead to acceptance of the null hypothesis. Classify that conclusionas a Type I Error, a Type II Error, or a correct decision, if in fact the average math SAT score of students atthe school is equal not to 520.
A health provider saw that 48% of their members received their flu shot in recent years. The health care provider tried a new advertising strategy the following year, and they took a sample of members to test if the proportion who received their flu shot had changed. Determine the null and alternative hypothesis
If the level of significance for a test for independency was 5% and the p-value was 0.03, what would the conclusion be: a. Fail to reject the null hypothesis b. Reject the null hypothesis and accept the alternate hypothesis
According to the National Highway and Traffic Safety Administration, the proportion of fatal traffic accidents in the United States in which the driver had a positive blood alcohol concentration (BAC) is .36. Suppose a random sample of 105 traffic fatalities in the state of Hawaii results in 51 that involved a positive BAC. D) Check whether the conditions for hypothesis testing using the P-value approach are meet.
Among a simple random sample of 331 American adults who do not have a four-year college degree and are not currently enrolled in school, 48% said they decided not to go to college because they could not afford school. a) A newspaper article states that only a minority of the Americans who decide not to go to college do so because they cannot afford it and uses the point estimate from this survey as evidence. Conduct a hypothesis test to determine if these data provide strong evidence supporting this statement. b)Would you expect a confidence interval for the proportion of American adults who decide not to go to college because they cannot afford it to include 0.5? Explain.
develop a research question that can be addressed with the dependent-samples t test, making sure to state the null and alternative hypotheses (in words)
A snack food company produces a 454g bag of pretzels. Although the actual net weights deviate slightly and vary bag to bag, the company insists that the mean net weight of the bags to be 454g. Determine the null and alternate hypothesis as well as the classification of the hypothesis test as left, right, or two tailed.
If, in a one-tail hypothesis test where H0 is only rejected in the upper tail, the p-value=0.2047 and ZSTAT=+0.82, what is the statistical decision if the null hypothesis is tested at the 0.07 level of significance? What is the statistical decision?
A researcher hypothesizes that Drug A is more effective than Drug B. In conducting an analysis to test this hypothesis, how should the null hypothesis be stated?
When asked what it means for the result of a hypothesis test to be practically significant (or practically important), Tatum says this means that the P-value is small and the null hypothesis has been rejected. what is wrong about this?
