help with these
The accompanying table shows the maximum weights (in kilograms) for which one repetition of a half squat can be performed and the times (in seconds) to run a 10-meter sprint for 12 international soccer players. Complete parts (a) through (d) below. Click here to view the data table. Click here to view the table of critical values for the Pearson correlation coefficient. There is linear correlation. Interpret the correlation. Choose the correct answer below. O A. Increases in the maximum weight for which one repetition of a half squat can be performed cause time to run a 10-meter sprint to increase. O B. Based on the correlation, there does not appear to be a linear relationship between the maximum weight for which one repetition of a half squat can be performed and time to run a 10-meter sprint. O C. As the maximum weight for which one repetition of a half squat can be performed increases, time to run a 10-meter sprint tends to decrease. O D. Based on the correlation, there does not appear to be any relationship between the maximum weight for which one repetition of a half squat can be performed and time to run a 10-meter sprint. O E. As the maximum weight for which one repetition of a half squat can be performed increases, time to run a 10-meter sprint tends to increase. O F. Increases in the maximum weight for which one repetition of a half squat can be performed cause time to run a 10-meter sprint to decrease. (d) Use the table of critical values for the Pearson correlation coefficient to make a conclusion about the correlation coefficient. Let a = 0.01.A used car dealer says that the mean price of a three-year-old sports utility vehicle is $24,000. You suspect this claim is K incorrect and find that a random sample of 25 similar vehicles has a mean price of $24,879 and a standard deviation of $1975. Is there enough evidence to reject the claim at a = 0.05? Complete parts (a) through (e) below. Assume the population is normally distributed. . . . (b) Find the critical value(s) and identify the rejection region(s). What is(are) the critical value(s), to? to = 0 (Use a comma to separate answers as needed. Round to three decimal places as needed.) Determine the rejection region(s). Select the correct choice below and fill in the answer box(es) within your choice. (Round to three decimal places as needed.) O A. t OB. > O C.Step by Step Solution
