### Confidence Interval Analysis for 12th Grade Students' HeightsA random sample of 25 12th-grade students was selected to study their heights. The following parameters were observed:- **Sample Mean Height**: 167.5 centimeters- **Sample Standard Deviation**: 11.3 centimetersA technology tool is utilized for calculating a confidence interval, which requires the following inputs: sample size, sample mean, and sample standard deviation. The goal is to interpret the confidence interval using these parameters.#### Steps to Follow:1. **View the Technology Output**: - The output displays key statistics and the calculated confidence interval.2. **Parameters from Technology Output**: - Sample Size (N): 25 - Sample Mean: 167.5 cm - Standard Deviation (StDev): 11.300 cm - Standard Error of the Mean (SE Mean): 2.260 cm - 95% Confidence Interval (CI): (162.836, 172.164) cm3. **Interpreting the Confidence Interval**: - Choose the correct interpretation and fill in the blanks: - The true mean height of all 12th-grade students is estimated to be between **162** cm and **172** cm (rounded to the nearest integer).#### Breakdown of Technology Output:- **N**: Number of students in the sample.- **Mean**: Average height of the sample.- **StDev**: Variation of heights in the sample.- **SE Mean**: Standard error, which measures the accuracy of the sample mean.- **95% CI**: Range in which the true population mean is expected to fall, with 95% confidence.Overall, these calculations provide a statistical foundation for estimating the average height of 12th-grade students based on the sample data.

For an Economics test the mean score is 100 and the standard deviation is 10, and for an Accounting test the mean score is 50 and the standard deviation is 4. You are given the test scores of a student who took both tests. Determine on which test the student had a better score. Enter E if the student did better on the Economics test Enter A if the student did better on the Accounting test Enter S if the student did relatively the same on both tests. A student scores 125.6 on the Economics test and 60.2 on the Accounting test. The student did better/same on test.
