Exercise 11 – Using Statistics to Describe a Study Sample 1) The interval level of measurement used in this demograpic are age‚ income ($)‚ length of labor (hrs)‚ return to work (wks)‚ number of hours working per week. 2) The type of statistics used to describe the length of labor in this study descriptive‚ this being represented by mean and standard deviation in the data. Yes‚these are appropriate as they both can be calculated (varible n=30 and mean=14.63) at the interval level of measurements

Spectrophotometric Determination of an Equilibrium Constant Introduction: In this experiment‚ you will study the reaction between aqueous iron (III) nitrate‚ Fe(NO3)3‚ and potassium thiocyanate‚ KSCN. They react to produce the blood-red complex [Fe(SCN)]2+. Fe3+ + SCN- ( [Fe(SCN)]2+ The equilibrium constant expression may be expressed as: K = [pic] You will prepare a series of standard solutions that contain known concentrations of [Fe(SCN)]2+ and will determine
