### Analysis of Correlation Coefficient and Data Table#### Correlation Coefficient Analysis**Instructional Question:** Based on the graph below, which of the following values for the correlation coefficient is most likely?**Scatter Plot Graph:**- **X-axis:** Labeled as "X," ranging from 0 to 80.- **Y-axis:** Labeled as "Y," ranging from 0 to 140.- **Data Points:** A series of blue dots showing a scattered distribution. The overall trend appears to be a downward slope.**Interpretation of Graph:**The scatter plot displays a negative correlation between X and Y. As the value of X increases, the value of Y tends to decrease.**Possible Values for Correlation Coefficient:**Without specific options provided, it's essential to understand this graph likely shows a strong negative correlation, which would correspond to a correlation coefficient close to -1.#### Data Table Transcription**Table Structure:**The table contains 9 rows and 3 columns.

Concept explainers

Inverse Normal Distribution

The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.

Mean, Median, Mode

It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.

Z-Scores

A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.

There is statistically insignificant evidence to conclude that there is a correlation between the time women spend on the phone and their weight. Thus, the use of the regression line is not appropriate. There is statistically insignificant evidence to conclude that a woman who spends more time on the phone will weigh more than a woman who spends less time on the phone. There…
