**Title: Student Enrollment Preferences in Biology Course Sections****Introduction:**This dataset, adapted from Johnson (1980), explores the preferences of students for different sections of a biology course offered in Fall 2016. Each semester, the course is divided into seven sections, each taught at varying times and by different instructors. The aim is to determine if there is a statistically significant preference for certain sections of the course.**Dataset Overview:**The table below summarizes the number of students enrolled in each of the seven sections:| Section | 1 | 2 | 3 | 4 | 5 | 6 | 7 ||---------|----|----|----|----|----|----|----|| Number of Students | 18 | 12 | 25 | 23 | 8 | 19 | 14 |**Hypothesis Testing:**To determine if students have a preference for certain sections, perform a hypothesis test with a significance level of α = 0.05. Follow these five steps for hypothesis testing:1. **State the Hypotheses:** - Null Hypothesis (H0): There is no preference among the different sections; the distribution of students across sections is uniform. - Alternative Hypothesis (H1): There is a preference for certain sections; the distribution is not uniform.2. **Choose the Significance Level:** - Significance level (α) = 0.053. **Calculate the Test Statistic:** - Use a chi-square test for goodness of fit since we are comparing observed frequencies with expected frequencies.4. **Determine the Critical Value/Decision Rule:** - Critical value from chi-square distribution table based on degrees of freedom (df = n - 1, where n = number of sections).5. **Make the Decision:** - Compare the calculated chi-square statistic to the critical value. If the chi-square statistic exceeds the critical value, reject the null hypothesis.Through this method, educators and researchers can assess whether specific sections of the course are more popular, which could inform scheduling and instructor assignment decisions in future semesters.

You place all of the cups upside down on a table but under one of the cups you place a chocolate frog. You know where the chocolate is but your sister does not. You ask your sister to choose the cup under which she thinks there is a frog. stal median hourly earnings by sex as reported by the Australian Bureau of statistics, cteristics of Employment, Australia, August 2021. 1 (a) What are the odds against your sister selecting the cup with the chocolate frog hidden underneath it? Your sister chooses a cup but you do not reveal what is underneath. Instead you overturn 24 other cups under which you know there is no frog. You then ask your sister if she wants to look under the cup she originally chose or if instead she would like to choose the final cup that remains upside down. She chooses to alter her choice and thus chooses to look under the other cup that…
To determine if patrons are satisfied with performance quality, a theater surveys patrons at an evening performance by placing a paper survey inside their programs. All patrons receive a program as they enter the theater. Completed surveys are placed in boxes at the theater exits. On the evening of the survey, 500 patrons saw the performance. One hundred surveys were completed, and 70% of these surveys indicated dissatisfaction with the performance. Should the theater conclude that patrons were dissatisfied with performance quality? Explain. Question content area bottom Part 1 Should the theater conclude that patrons were dissatisfied with performance quality? Select all that apply. A. No, because there was sampling bias as those who had strong feelings about the performance (positive or negative) may be more likely to return the survey. B. No, because there was measurement bias as patrons will give a response that is more favorable than the…
