1 1 point You plan to use a correlation to test whether amount of time spent outside, (on average, per day) is different for people who own different numbers of dogs. Which of the following would be an appropriate alternative hypothesis? )r is greater than 0 (predicting a positive correlation) O r does not equal O (predicting a correlation without directionality specified) O r is less than 0 (predicting a negative correlation)2 2 points Calculate the correlation between minutes spent outside per day and number of dogs owned. Here is a link to the same data table shown below, so that you can copy or download it: data set for this problem. Number of Time Outside ID Dogs Owned (min/day) 30 30 ON 75 15 4 45 45 10 30 0 45 0 60 13 90 14 75 15 10 16 1 90 Round your answer to the nearest hundredth. Type your answer.3 1 point Determine the critical value against which to compare your results from the previous step. Don't forget to look back at your original hypothesis! Do not round your response.

O Fail to reject the null hypothesis; there is a significant correlation but it is not in the hypothesized direction. Fail to reject the null hypothesis; there is not a significant correlation. Reject the null hypothesis; there is a significant positive correlation. O Reject the null hypothesis; there is a significant negative correlation.5 1 point You plan to use a correlation to test whether people spend more time on hobbies if they spend less time on work. Which of the following would be an appropriate alternative hypothesis? r does not equal 0 (predicting a correlation without directionality specified) O r is greater than 0 (predicting a positive correlation) O r is less than 0 (predicting a negative correlation)6 2 points Calculate the correlation between hours per week spent on hobbies and hours per week spent on work.
