Ashareholders' group, in lodging a protest, claimed that the mean tenure for a chief executive officer (ceo) was at least nine years. a survey of companies reported in the wall street journal found a sample mean tenure of x = 7.07 years for ceos with a standard deviation of s = 6.38 years. (a) choose the correct hypotheses that can be used to challenge the validity of the claim made by the shareholders' group. h0: μ years ha: μ years (b) assume that 85 companies were included in the sample. what is the p value for your hypothesis test? if required, round your answer to four decimal places. (c) at α = 0.01, what is your conclusion? we the null hypothesis. we conclude that the mean tenure for a ceo is shorter than nine years.

Part one: measurements 1. measure your own height and arm span (from finger-tip to finger-tip) in inches. you will likely need some from a parent, guardian, or sibling to get accurate measurements. record your measurements on the "data record" document. use the "data record" to you complete part two of this project. name relationship to student x height in inches y arm span in inches archie dad 72 72 ginelle mom 65 66 sarah sister 64 65 meleah sister 66 3/4 67 rachel sister 53 1/2 53 emily auntie 66 1/2 66 hannah myself 66 1/2 69 part two: representation of data with plots 1. using graphing software of your choice, create a scatter plot of your data. predict the line of best fit, and sketch it on your graph. part three: the line of best fit include your scatter plot and the answers to the following questions in your word processing document 1. 1. which variable did you plot on the x-axis, and which variable did you plot on the y-axis? explain why you assigned the variables in that way. 2. write the equation of the line of best fit using the slope-intercept formula $y = mx + b$. show all your work, including the points used to determine the slope and how the equation was determined. 3. what does the slope of the line represent within the context of your graph? what does the y-intercept represent? 5. use the line of best fit to you to describe the data correlation.
