The scatterplot below shows?-weak positive correlation-strong positive correlation-weak negative correlation-weak positivve correlation The image features a scatter plot graph used for representing data points where two variables are measured.### Description of the Graph:- **Axes:** - The horizontal axis is labeled "X measure" with values ranging from 0 to 60. - The vertical axis is labeled "Y measure" with values ranging from 0 to 120.- **Data Points:** - The scatter plot displays numerous data points (depicted as blue diamonds) spread across the graph. - The data points show a positive correlation, where an increase in the X measure generally corresponds to an increase in the Y measure. - The points are more densely populated at lower values of both X and Y measures and gradually spread out as the values increase.### Analysis:- The pattern suggests a potential linear relationship between the variables measured on the X and Y axes. - This graph can be used to assess the strength and direction of a linear relationship, which can be further analyzed with statistical methods like correlation coefficients or regression analysis.

Which of the following best describes the Pearson correlation for these data?
Fifty-four wild bears were anesthetized, and their weights and chest sizes were measured. Results are showing in the graph below. IS there sufficient evidence to support the claim that there is a linear correlation between weights of bears and their chest sizes? When measuring an anesthetized bear, is it easier to measure chest size than weight? If so, does it appear that a measured chest size can be used to predict the weight? Correlation Results Correlation coeff r:0.963141 Critical r ±0.2680855 P-value (two-tailed) 0.000
Police sometimes measure shoe prints at crime scenes so that they can learn something about criminals. Listed below are shoe print lengths, foot lengths, and heights of males. Construct a scatterplot, find the value of the linear correlation coefficient r, and find the P-value of r. Determine whether there is sufficient evidence to support a claim of linear correlation between the two variables. Based on these results, does it appear that police can use a shoe print length to estimate the height of a male? Use a significance level of a= 0.01. Shoe Print (cm) | 28.8 Foot Length (cm) 24.8 Height (cm) 30.8 30.4 31.1 28.6 24.6 27.8 26.1 25.3 177.6 179.2 179.2 169.4 169.5
A personnel manager wants to find out if a test carried out during an employee’s interview and a skills assessment at the end of basis training is a guide to performance after working for the company for one year. The table below shows the results of the interview test of 10 employees and their performance after one year. Please provide the Pearson r correlation coefficient for the indicated data. How would you rate the correlation coefficient (strong, moderate, weak)?

A study of elementary school children, ages 6 to 11, finds a high positive correlation between shoe size x and score y on a test of reading comprehension. The observed correlation is most likely due to: the effect of a lurking variable, such as age or years of reading experience. a mistake, because the correlation must be negative. cause and effect (larger shoe size causes higher reading comprehension). reverse cause and effect (higher reading comprehension causes larger shoe size).
