A Recent Survey Of 8,000 High School Students Found That The Mean Price Of A Prom Dress Was $ 195.00 \$195.00 $195.00 With A Standard Deviation Of $ 12.00 \$12.00 $12.00 . Alyssa Thinks That Her School Is More Fashion-conscious And That Students Spent More Than
Introduction
Understanding the Problem Alyssa's assumption about her school's fashion-consciousness is based on the mean price of prom dresses in her school, which she believes is higher than the national average of . To test her hypothesis, we need to understand the concept of standard deviation and how it relates to the mean price of prom dresses.
What is Standard Deviation?
Defining Standard Deviation Standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean, while a high standard deviation indicates that the values are spread out over a wider range. In this case, the standard deviation of indicates that the prices of prom dresses vary by on average.
Hypothesis Testing
Testing Alyssa's Hypothesis To test Alyssa's hypothesis, we need to calculate the z-score, which is a measure of how many standard deviations an element is from the mean. The z-score formula is: z = (X - μ) / σ, where X is the value, μ is the mean, and σ is the standard deviation. If the z-score is greater than 2, we can reject the null hypothesis that the mean price of prom dresses in Alyssa's school is equal to the national average.
Calculating the Z-Score
Calculating the Z-Score for Alyssa's School Let's assume that the mean price of prom dresses in Alyssa's school is . We can calculate the z-score using the formula: z = (220 - 195) / 12 = 25 / 12 = 2.08. Since the z-score is greater than 2, we can reject the null hypothesis and conclude that the mean price of prom dresses in Alyssa's school is higher than the national average.
Conclusion
Implications of the Results The results of this study have implications for Alyssa's school and its students. If the mean price of prom dresses in Alyssa's school is indeed higher than the national average, it may be due to a variety of factors, including the school's fashion-consciousness, the availability of high-end prom dress stores, or the cultural and socioeconomic background of the students. Regardless of the reason, the results of this study suggest that Alyssa's school is more fashion-conscious than the national average.
Limitations of the Study
Limitations of the Study There are several limitations to this study. First, the sample size of 8,000 high school students may not be representative of all high school students. Second, the survey may not have captured the full range of prom dress prices, as some students may have spent more or less than the reported prices. Finally, the study assumes that the mean price of prom dresses is a reliable indicator of a school's fashion-consciousness, which may not be the case.
Future Research Directions
Future Research Directions Future research directions include investigating the factors that to a school's fashion-consciousness, such as the availability of high-end prom dress stores, the cultural and socioeconomic background of the students, and the school's policies and practices related to prom dress. Additionally, researchers could explore the relationship between prom dress prices and other factors, such as student body size, school type, and geographic location.
