**Analysis of Auditory Defects in Elementary School Children**In previous screenings of elementary school children in a large city, 25% were found to have auditory defects. Recently, a study of 200 children who were screened found that 63 had such defects. This analysis explores whether there is a significant increase in the proportion of children with auditory defects. The test is conducted at a significance level of \(\alpha = 0.10\). Answers should be rounded to three decimal places and any interim calculations to four decimal places.### Statistical Analysis1. **Test Statistic**: The calculated test statistic is **2.123**.2. **P-value Calculation**: Using the test statistic from above, determine the p-value. (Input field provided for response).3. **Critical Value**: Identify the critical value for this test. (Input field provided for response).This exercise applies hypothesis testing to evaluate changes in health metrics over time. Understanding the application of statistical tests helps in decision-making and resource allocation in public health contexts.

On occasion, medical studies need to model the proportion of the population that has a disease and compare that to observed frequencies of the disease actually occurring. Suppose the end-stage renal failure in south-west Wales was collected for different age groups. Do the data in the table show that the observed frequencies are in agreement with proportion of people in each age group? Test at the 1% level.

According to data from the Tobacco Institute Testing Laboratory, a certain brand of cigarette contains an average of 1.4 milligrams of nicotine. An advocacy group questions this figure, and commissions an independent test to see if the the mean nicotine content is higher than the industry laboratory claims. The test involved randomly selecting n = 15 cigarettes, measuring the nicotine content (in milligrams) of each cigarette. The data is given below: 1.8, 1.8, 1.5, 1.1, 1.4, 1.3, 1.3, 1.4, 1.1, 1.3, 1.6, 1.2, 1.8, 1.4, 1.6; Download .csv file Not sure how to perform some of the tasks with R-Studio?

Researchers examined the influence of a television program on children's aggressiveness. The number of aggressive responses was measured during an observation period after viewing the television program. Imagine that the known national average for number of aggressive responses typically performed by children who do not watch television is 6.847. Use the data below to conduct an analysis to determine if the number of aggressive responses on average is different from the national average. The data for this study can be found below, answer questions based on data. What is the null and alternative hypotheses in words and symbols? Is the assumption(s) met? Please explain your answer and proceed with the analysis even if the assumption(s) is not met. What do you conclude from your analysis?
