**Sales Data Analysis for Adidas**The sales of Adidas have been fluctuating over the past few years. Upon analysis, it was determined that the sales data follows a bell-shaped distribution with a mean of 100 and a standard deviation of 15. As an analyst, you have been hired by Adidas to find out specific information regarding the sales distribution. **Problem Statement**What is the range of z-scores for sales between 85 and 130?**Select One of the Following Options:**A) [-2, 2]B) [85, 115]C) [-1, 2]D) [85, 130]E) [-1, 1]---**Explanation:**- The problem involves finding the z-scores for given sales values when the sales follow a normal distribution.- The z-score is a measure of how many standard deviations a data point is from the mean. **Links and Helpful Concepts:**- **Bell-shaped Distribution**: [Read more](https://www.example.com/link_to_more_explained_data)- **Finding Z-scores**: To find the z-score, use the formula: \[ z = \frac{(X - \mu)}{\sigma} \] where \(X\) is the value, \(\mu\) is the mean, and \(\sigma\) is the standard deviation.**Steps to Compute Z-scores:**1. For \(X = 85\): \[ z = \frac{(85 - 100)}{15} = \frac{-15}{15} = -1 \]2. For \(X = 130\): \[ z = \frac{(130 - 100)}{15} = \frac{30}{15} = 2 \]Hence, the range of z-scores is \([-1, 2]\).---**Correct Answer:**C) \([-1, 2]\)This analysis allows understanding how sales data points deviate from the mean and underlines the importance of normal distribution in sales data assessment.
