Project Part 5 - Final Report You Will Submit ✓ Solved

Project Part 5 - Final Report You will submit a final report, written in Word

This assignment requires the submission of a comprehensive final report that synthesizes the findings from Parts 1 through 4 of a statistics project. The report must be written in APA format and include three well-structured paragraphs that summarize the entire project, including the article reviewed, the statistical analyses performed, and the interpretations of the results. The submission should reflect careful review of instructor feedback from previous weeks, ensuring that the report is coherent, flows naturally with transitions, and is written in third person. It should avoid simple listing of calculations, instead focusing on describing the results clearly for a non-statistical audience, emphasizing implications and interpretations rather than technical details. The report will be submitted via SafeAssign on BlackBoard.

Sample Paper For Above instruction

The selected article for this project was sourced from [Insert Source], available at [Insert Link]. This study focused on [briefly describe the subject of the study, e.g., evaluating the average daily screen time among teenagers]. The population under investigation consisted of [define the population, e.g., all high school students in the urban district], with a sample drawn from this population consisting of [number of participants, e.g., 150 students]. The key statistic of interest from this study was the sample mean of [the variable measured, e.g., daily hours spent on screens], which served as the basis for analyzing the study’s claims. The article tested two primary claims: first, that the average screen time exceeds [value], and second, that the proportion of students who meet certain criteria (e.g., exceeding a screen time threshold) is greater than a specified proportion. The hypotheses for these tests were articulated accordingly: the null hypothesis posited no difference or no effect, while the alternative hypothesized a difference or effect in the specified direction.

Addressing the claim about the mean, the sample statistics showed a mean of [calculated mean], with a standard deviation of [standard deviation]. The median was [median], and the quartiles ranged from [Q1] to [Q3]. The sample size was [number of observations]. A 95% confidence interval for the population mean was calculated as [interval], which suggests that we are 95% confident the true average lies within this range. The hypothesis test was conducted at an alpha level of 0.05, yielding a test statistic of [value] and a p-value of [value]. Since the p-value was [less than / greater than] 0.05, we [reject / fail to reject] the null hypothesis, indicating that there is sufficient evidence to support the claim that the mean exceeds [value]. This result implies that [interpretation of the conclusion].

Regarding the claim about the proportion, the sample included [sample size], with [number of successes, e.g., students exceeding the threshold] and a resulting proportion of [proportion]. The 95% confidence interval for this proportion was [interval], meaning we are 95% confident that the true proportion in the population falls within this range. The hypothesis test involved an alpha of 0.05, with a test statistic of [value] and a p-value of [value]. Based on these results, we [reject / do not reject] the null hypothesis that the true proportion is equal to [value]. This supports the conclusion that the proportion of [successes] in the population is [greater than / less than / equal to] the hypothesized value. Overall, these analyses provide insight into [discuss the broader implications or contributions of these findings], emphasizing how statistical inference aids in understanding population characteristics from sample data.
