Is the average time to complete an obstacle course shorter when a patch is placed over the right eye than when a patch is placed over the left eye? Thirteen randomly selected volunteers first completed an obstacle course with a patch over one eye and then completed an equally difficult obstacle course with a patch over the other eye. The completion times are shown below. "Left" means the patch was placed over the left eye and "Right" means the patch was placed over the right eye. Time to Complete the Course Right 42 43 45 46 43 43 40 46 Left 43 43 47 51 41 45 40 47 Assume a Normal distribution. What can be concluded at the the αα = 0.01 level of significance level of significance? For this study, we should use Select an answer z-test for the difference between two population proportions t-test for the difference between two dependent population means t-test for the difference between two independent population means t-test for a population mean z-test for a population…
10. The distance that a cyclist rides each day is what sort of data: a. Discrete b. Continuous
How do I determine each individual time on this box plot? i dont know how Im supposed to answer the questions following without knowing each individual time.
You measure the length of 11 bullfrogs (Lithobates (=Rana) catesbeiana), and then measure how for each frog can jump. You get the following results (size in mm, jump distance in cm). Size 155 127 136 135 158 145 136 172 158 162 162 Distance 71.0 70.0 100.0 120.0 103.3 116.0 109.2 105.0 112.5 114.0 122.9 You find the following results: SSx = 2,094.55 SSy = 3,218.99 SScp = 731.36 n = 11 ¯y = 103.99 ¯x = 149.64 SSresid = 2,963.61 a) Give the equation of the least squares line. b) Give both the test statistic and the table value. Make sure you give H0, H1, α, etc. and state your conclusion. c) Make a scatterplot of these data and fit the least squares line. d) Make a residual plot of these data and comment on it. e) Calculate R 2 and explain. Is R 2 even appropriate here (what is your answer to (b)?)
An estimate of the variation between the groups is the a. Mean Square due to Error. b. Sum of Squares Total. c. Sum of Squares due to Treatments. d. Sum of Squares due to Error.
