You are given the following hypotheses. h0: μ = 40 ha: μ ≠ 40 we know that the sample standard deviation is 10 and the sample size is 60. for what sample mean would the p-value be equal to 0.05? assume that all conditions necessary for inference are satisfied. (round your answers to two decimal places.) smaller mean x = larger mean x = you may need to use t.

Look at this system of equations. -3x + 3y = 12 y = x + 4 the solution set of this system is best explained by which of these statements? a) the graphs of the equations are the same line because the equations have the same slope and the same y-intercept. the system has infinitely many solutions. b) the graphs of the equations are parallel lines because they have the same slope but different y-intercepts. the system has no solution. c) the graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. the system has exactly one solution. d) the graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. the system has exactly one solution.
