### Formulating Hypotheses#### Question:Which of the following statements could be used to develop a null and alternative hypothesis?#### Explanation:To answer this question, it is essential to understand the concepts of null and alternative hypotheses. A null hypothesis (denoted as $ H_0 $) typically states that there is no effect or no difference, and it serves as the default or baseline assumption. An alternative hypothesis (denoted as $ H_1 $ or $ H_A $), on the other hand, suggests that there is an effect or a difference.In a scientific or statistical investigation, you will seek to either reject or fail to reject the null hypothesis based on the evidence provided by your data.##### Examples of Hypothesis Statements:- Null Hypothesis ($ H_0 $): There is no significant difference in the test scores between students who attended the review session and those who did not.- Alternative Hypothesis ($ H_1 $): There is a significant difference in the test scores between students who attended the review session and those who did not.Remember, the null hypothesis is assumed to be true until evidence suggests otherwise, thereby shifting the burden of proof to the alternative hypothesis. ### Claims Assessment ExerciseThis exercise contains a list of statements that involve various claims related to societal and educational topics. Each statement reflects different aspects such as governance, public opinion, healthcare, education, and social media usage. Read through each statement carefully, and consider their implications and validity.1. **A governor claimed that more than 76% of residents welcomed the stay-at-home order.**2. **The protesters claimed that less than half of small businesses had received aid.**3. **Hospitals claimed that they did not have the PPE required to keep their personnel safe.**4. **Capitol High School said that the SAT standard deviation was 22.5 points.**5. **She claimed that the number of Facebook accounts was greater than the number of Twitter accounts.**These statements may be used to spark discussions or critical thinking exercises on data interpretation, the accuracy of claims, and the different sources of information. Each point can be analyzed for its statistical, social, and practical implications in a classroom setting. There are no graphs or diagrams accompanying these statements.

Concept explainers

Inverse Normal Distribution

The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.

Mean, Median, Mode

It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.

Z-Scores

A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
