Is the right arm or left arm stronger? Twenty five right handed people were studied. They were asked to do as many bicep curls as possible, first with their right arm and then with their left arm. Note:The differences were calculated as right-left. The 95% confidence interval for the true mean difference is (-9.242, 0.2472). Which of the following statements is the correct interpretation? Group of answer choices There is convincing evidence that the right arm can perform, on average, a different number of curls than the left arm. The left arm can perform more bicep curls than the right arm. The right arm can perform more bicep curls than the left arm. There is not enough evidence to say that the right arm and left arm can perform a different number of curls on average.

How is the number of vertices for a prism related to the name of the prism

After a dreary day of rain, the sun peeks through the clouds and a rainbow forms. you notice the rainbow is the shape of a parabola. the equation for this parabola is y = -x2 + 36. graph of a parabola opening down at the vertex 0 comma 36 crossing the x–axis at negative 6 comma 0 and 6 comma 0. in the distance, an airplane is taking off. as it ascends during take-off, it makes a slanted line that cuts through the rainbow at two points. create a table of at least four values for the function that includes two points of intersection between the airplane and the rainbow. analyze the two functions. answer the following reflection questions in complete sentences. what is the domain and range of the rainbow? explain what the domain and range represent. do all of the values make sense in this situation? why or why not? what are the x- and y-intercepts of the rainbow? explain what each intercept represents. is the linear function you created with your table positive or negative? explain. what are the solutions or solution to the system of equations created? explain what it or they represent. create your own piecewise function with at least two functions. explain, using complete sentences, the steps for graphing the function. graph the function by hand or using a graphing software of your choice (remember to submit the graph).

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.
