Astudy of the pay of corporate chief executive officers (ceos) examined the increase in cash compensation of the ceos of 104 companies, adjusted for inflation, in a recent year. the mean increase in real compensation was x¯ = 6.9%, and the standard deviation of the increases was s = 55%. is this good evidence that the mean real compensation µ of all ceos increased that year? the hypotheses are

h0: %u03bc = 0 (no increase) ha: %u03bc > 0 (an increase)

because the sample size is large, the sample s is close to the population %u03c3 , so take %u03c3 = 55%.

(a) sketch the normal curve for the sampling distribution of x when h0 is true. shade the area that represents thep-value for the observed outcome x = 6.9%.

(b) calculate the p -value.

How do i do this activity, is appreciated

The table shows the relationship between the number of cups of cereal and the number of cups of raisins in a cereal bar recipe: number of cups of cereal number of cups of raisins 8 2 12 3 16 4 molly plotted an equivalent ratio as shown on the grid below: a graph is shown. the title of the graph is cereal bars. the horizontal axis label is cereal in cups. the x-axis values are 0, 20, 40, 60, 80,100. the vertical axis label is raisins in cups. the y-axis values are 0, 10, 20, 30, 40, 50. a point is plotted on the ordered pair 40,20. which of these explains why the point molly plotted is incorrect? (a) if the number of cups of cereal is 40, then the number of cups of raisins will be10. (b)if the number of cups of raisins is 40, then the number of cups of cereal will be10. (c) if the number of cups of cereal is 40, then the number of cups of raisins will be 80. (d) if the number of cups of raisins is 40, then the number of cups of cereal will be 80.
