For a data set of chest sizes (distance around chest in inches) and weights (pounds) of ten anesthetized bears that were measured, the linear correlation coefficient is r=0.906. Use the table available below to find the critical values of r. Based on a comparison of the linear correlation coefficientr and the critical values, what do you conclude about a linear correlation? Click the icon to view the table of critical values of r. The cnitical values are (Type integers or decimals. Do not round. Use a comma to separate answers as needed.) it:
After a first-order model was fitted to the data, the coefficient of correlation between the usage in hours per week (x) of a particular brand of computer and the maintenance cost of the computer (y) is calculated as 0.84. Interpret the value of the coefficient of determination.
A study found that the mean amount of time cars spent in drive-throughs of a certain fast-food restaurant was 138.7 seconds. Assuming drive-through times are normally distributed with a standard deviation of 31 seconds, complete part (a) through (d) below. Click here to view the standard normal distribution table (page 1). Click here to view the standard normal distribution table (page 2). (a) What is the probability that a randomly selected car will get through the restaurant's drive-through in less than 103 seconds? The probability that a randomly selected car will get through the restaurant's drive-through in less than 103 seconds is 0.1251. (Round to four decimal places as needed.) (b) What is the probability that a randomly selected car will spend more than 191 seconds in the restaurant's drive-through? The probability that a randomly selected car will spend more than 191 seconds in the restaurant's drive-through is 0.0458. (Round to four decimal places as needed.) (c) What…

For a sample of eight bears, researchers measured the distances around the bears' chests and weighed the bears. Minitab was used to find that the value of the linear correlation coefficient is r = 0.862. Using a = 0.05, determine if there is a linear correlation between chest size and weight. What proportion of the variation in weight can be explained by the linear relationship between weight and chest size? Click here to view a table of critical values for the correlation coefficient. a. Is there a linear correlation between chest size and weight? O A. No, because the absolute value of r exceeds the critical value of 0.707. O B. Yes, because r falls between the critical values of -0.707 and 0.707. O C. Yes, because the absolute value of r exceeds the critical value of 0.707. O D. The answer cannot be determined from the given information. b. What proportion of the variation in weight can be explained by the linear relationship between weight and chest size? (Round to three decimal…

determine whether suicide and homicide rates in metropolitan areas around the country are correlated. a sample of 10 metropolitan areas with their rates (number per 100,000), of suicide and homicide. computed the correlation coefficient of 0.70.
A professor believed that there is a correlation between people’s weights and number of times they eat out. He recorded a group of students’ weights (measured in lbs.) and the number of times they ate out last week. The r value was 0.90. We can tell that the correlation between students’ weights (measured in kilogram) and the number of times they ate out last week is: Bigger than 0.9 0.90 Smaller than 0.9 We cannot tell ( don't hand writing solution)
A researcher studied the relationship between the amount of carbohydrates (x) and the amount of salt (y) in different food products. sample of 36 food products yielded these calculations: r = -0.1245, ŷ=0.5545– 0.1636x According to the correlation, if a food contains more carbohydrates, is it likely to contain more salt or less salt? Why or why not?
