This tutorial explains how to perform linear regression on a TI-84 calculator. Linear regression is a method we can use to understand the relationship between an explanatory variable, x, and a response variable, y. She has two businesses, including a martial arts gym in Texas. Mackenzie Maxwell is a small business owner. Although it is possible to do statistical calculations on the TI-84, it is much more practical to use a program such as SPSS. Perform a Two-Way ANOVA by entering your second independent variable as another data set on your calculator.

A quality control specialist calculated the z-score associated with his own salary and found it was -2.50. Calculate the z-score for each dog's weight and then determine which dog is more underweight? (To receive credit, you must write the formula and the values you used.) (5 pts) 4) The ASQ (American Society for Quality) regularly conducts a salary survey of its membership, primarily quality management professionals. The Akita weighs 97 pounds, and the Boston Terrier weighs 16 pounds. One dog lover owns an underweight Akita and an underweight Boston Terrier. Adult male Boston Terriers weigh an average of 18.5 pounds with a standard deviation of 2.7 pounds. Your drawing should be much more specific than what your calculator will give you.) e) What are the best measures for the center and spread of this distribution? Why? 3) Adult male Akitas weigh an average of 115 pounds with a standard deviation of 10.4 pounds. (Be sure to label your scale as well as the fences, each value from the 5-number summary, and any outliers. (To receive credit, you must write the formulas and the values you used.) c) Are there any outliers? If so, what are they? d) Draw a modified boxplot using an appropriate scale. b) Calculate the fences for a modified boxplot. I encourage you to check your boxplot with your calculator but don't let this be your first step. Below is a set of contrived data and steps for finding the values you will need for this boxplot. g) Using the Empirical Rule, between what two values will approximately 95% of the data fall? (To receive credit, you must write your work.)ΔΆ) The best way to learn about a boxplot is to draw one by-hand. d) What is the best measure for the center of this distribution, the mean or the median? e) What is the best measure for the spread of this distribution, the range, the standard deviation, or the Inter Quartile Range? f) Is it appropriate to use the Empirical Rule to make approximations of this data set? Explain. skewed right or left, symmetric), and whether or not there are any possible outliers. unimodal, bimodal, uniform), the skew/symmetry (i.e. b) Are the calculations you found for part (a) statistics or parameters? c) Describe the shape of the distribution using correct statistical vocabulary by noting the modality (i.e. What is the mean of this sample data? (round to two decimal places) What is the median of this sample data? What is Q1 and Q3? What is the IQR of this sample data? What is the standard deviation of this sample data? (round to three decimal places). (To do this enter the data in L1 and then go to STAT-CALC-1 VarStats.) List the data you entered into L1.
