### Hypothesis Testing and The Rejection Region**Introduction:**A group of gemologists is interested in studying the average money spent on an engagement ring. In 2020, the average amount spent was $6,100. Due to the effects of COVID-19, the gemologists hypothesize that the average spending has increased in 2021. They decide to carry out a hypothesis test to explore this assumption.**Question:**If the gemologists carry out a hypothesis test, what value forms the rejection region? Select the single best answer choice from the options below:1. Alternative Hypothesis2. Critical Value3. Null Hypothesis*Choose the correct answer to understand the hypothesis testing process better and learn about the concept of the rejection region.*### Explanation:- **Null Hypothesis (H0):** A statement that there is no effect or no difference, and it represents the status quo. In this case, the null hypothesis might be that the average money spent in 2021 is still $6,100. - **Alternative Hypothesis (H1):** A statement that contradicts the null hypothesis. It suggests there is an effect or a difference. Here, the alternative hypothesis would be that the average amount spent in 2021 has increased compared to 2020. - **Critical Value:** A threshold value that defines the boundary for rejecting the null hypothesis. It is determined based on the significance level (α) chosen for the test (commonly 0.05). This value forms the "rejection region."**Answer:**The **critical value** forms the rejection region. If the test statistic falls into this region, the null hypothesis is rejected in favor of the alternative hypothesis.Understanding these concepts is crucial for interpreting the results of hypothesis tests and making informed conclusions based on statistical evidence.

We know that, null hypothesis is hypothesis of no difference. The hypothesis which is stated against…

The Trial Urban District Assessment (TUDA) is a government-sponsored study of student achievement in large urban school districts. TUDA gives a mathematics test scored from 0 to 500. A score of 262 is a "basic" mathematics level, and a score of 299 is "proficient." Scores for a random sample of 1100 eighth-graders in Dallas had x = 264 with standard error 1.3.

Workers' Distractions. A recent study showed that the modern working person experiences an average of 2.1 hours per day of distractions (phone calls, e- mails, impromptu visits, etc.). A random sample of 16 workers for a large corporation found that these workers were distracted an average of 1.8 hours per day and the standard deviation was 20 minutes. Estimate the true mean population distraction time with 90% confidence, and compare your answer to the results of the study. (1.654,1.946). Mean of the study is outside or "different" from the result of our study.
