Head movement evaluations are important because disabled individuals may be able to operate communications aids using head motion. A paper reported the accompanying data on neck rotation (in degrees) for 14 subjects both in the clockwise direction (CL) and in the counterclockwise direction (CO). For purposes of this exercise, you can assume that the 14 subjects are representative of the population of adult Americans. Subject: Find the df. df = 13 11 12 13 14 59.2 59.2 55.8 38.7 59.8 47.5 64.5 34.2 Based on these data, is it reasonable to conclude that mean neck rotation is greater in the clockwise direction than in the counterclockwise direction? Carry out a hypothesis test using a significance level of 0.01. (Use HCL -#co¹) Find the test statistic. (Round your answer to two decimal places.) t = 0.60 x CL: 2 CO: 3 6 7 5 51.1 70.8 10 54.7 63.6 9 Use technology to find the P-value. (Round your answer to four decimal places.) P-value = 0.2793x State your conclusion. 57.6 35.7 54.5 56.8 77.3 51.6 44,3 52.1 60.2 52.7 47.2 65.6 71.4 48.8 53.1 66.3 O Fail to reject H. We have convincing evidence that mean neck rotation is greater in the clockwise direction than in the counterclockwise direction. Fail to reject H. We do not have convincing evidence that mean neck rotation is greater in the clockwise direction than in the counterclockwise direction. O Reject H. We do not have convincing evidence that mean neck rotation is greater in the clockwise direction than in the counterclockwise direction. O Reject H. We have convincing evidence that mean neck rotation is greater in the clockwise direction than in the counterclockwise direction.

You are interested in the relationship between gender and violent victimization. You have the data below: Victimization No Yes Total Gender b. Interpret Lambda. Male 150 50 200 Female 190 10 200 Total 340 60 400 a. Calculate Lambda. If needed, take a picture of your work and insert directly into the workspace.

Which scatter plot shown has a correlation coefficient, r, closest to 0?

A group of researchers measured how funny people rated a cartoon when they were in one of two groups: holding a pen in their teeth (forcing them to smile) or holding a pen in their lips (forcing them to frown). For this study, identify the independent variable and the dependent variable. Justify your response.

The horsepower (Y, in bhp) of a motor car engine was measured at a chosen set of values of running speed (X, in rpm). The data are given below (the first row is the running speed in rpm and the second row is the horsepower in bhp): rpm 1100 1400 1700 2300 2700 3200 3500 4000 4600 5200 5600 6100 Horsepower (bhp) 50.2 64.29 67.83 98.56 131.09 163.65 161.55 198.62 226.03 254.71 283.63 299.81 The mean and sum of squares of the rpm are 3450.0000 rpm and 173900000.0000 rpm 22 respectively; the mean of the horsepower values is 166.6642 bhp and the sum of the products of the two variables is 8506152.0000 rpm bhp.    Given Values: a) Slope: 0.052 b) Intercept: -11.694 c) 95% Confidence Interval when the standard error of the estimate of the slope coefficient was found to be 0.001160: (0.0494, 0.0546) please answer the following: Part e)Without extending beyond the existing range of speed values or changing the number of observations, we would expect that increasing the variance of the…
