A group of students measure the length and width of a random sample of beans. They are interested ininvestigating the relationship between the length and width. Their summary statistics are displayed in thetable below. All units, if applicable, are millimeters.Mean widthStandard deviation of widthMean heightStandard deviation of heightCorrelation coefficient7.560.87713.8941.7460.837Round your answers to three decimal places.The students are interested in using the width of the beans to predict the height. Calculate the slope ofthe regression equation.1.666Write the equation of the line of best fit that can be used to predict bean heights. Use a to representwidth and y to represent height.1.299 +1.666(x) x syntax error: this is not an equation.What fraction of the variability in bean heights can be explained by the linear model of bean height vs.width? Express your answer as a decimal.0.7006If, instead, the students are interested in using the height of the beans to predict the width, calculate theslope of this new regression equation.Write the equation of the line of best fit that can be used to predict bean widths. Use a to representheight and y to represent width.

Use the given data values (a sample of female arm circumferences in centimeters) to identify the corresponding z scores that are used for a normal quantile plot, then identify the coordinates of each point in the normal quantile plot. Construct the normal quantile plot, then determine whether the data appear to be from a population with a normal distribution. 33.9, 37.9, 43.8, 32.8, 40.1 Question content area bottom Part 1 List the z scores for the normal quantile plot. Part A -List the z scores for the normal quantile plot. Part B- Identify the coordinates of each point in the normal quantile plot. Use ordered pairs for the form (x,y), where x is the sorted arm circumferences in ascending order, and y is the corresponding z score. Part C- Do the data come from a normally distributed population?
The data found below measure the amounts of greenhouse gas emissions from three types of vehicles. The measurements are in tons per year, expressed as CO2 equivalents. Use a 0.025 significance level to test the claim that the different types of vehicle have the same mean amount of greenhouse gas emissions. Based on the results, does the type of vehicle appear to affect the amount of greenhouse gas emissions? : Click the icon to view the data. What are the hypotheses for this test? Data Table O A.
