In order to compare the durability of four different brands of golf balls (ALPHA, BEST, CENTURY, and DIVOT), the National Golf Association randomly selects five balls of each brand and places each ball into a machine that exerts the force produced by a 250-yard drive. The number of simulated drives needed to crack or chip each ball is recorded. The results are given in the table. Let μALPHA, μBEST, μCENTURY, and μDIVOT represent treatment means for ALPHA, BEST, CENTURY, and DIVOT, respectively. ALPHA BEST CENTURY DIVOT 281 270 218 364 220 334 244 302 274 307 225 325 242 290 273 337 251 331 249 355 Download or transcribe the data in the table to Minitab and conduct an Analysis of Variance (α = .05). First, create a box plot of the data for initial assessment, then run the Minitab ANOVA, answering the following questions. Step 4 of 4: Referring to the One-way ANOVA table for Golf Balls, based on the p-value:

Suppose 4 brands of golf balls are compared by hitting a random sample of balls of each brand and recording the distance the balls travel. This is a CR design. Suppose the MSE = 24 and suppose the sample size for Brand C is 10. Further, suppose Tukey Multiple Comparison Procedure shows that Brand C's mean distance exceeds all others. Suppose the sample mean for Brand C was 231 calculate the width of a 95% confidence interval for the true...

A sporting goods manufacturing company wanted to compare the distance traveled by golf balls produced using each of four different designs. Ten balls were manufactured with each design and were brought to the local golf course for the club professional to test. The order in which the balls were hit with the same club from the first tee was randomized so that the pro did not know which type of ball was being hit. All 40 balls were hit in...

In an experiment to investigate the performance of four different brands of spark plugs intended for use on a 125-cc motorcycle, five plugs of each brand were tested, and the number of miles (at a constant speed) until failure was observed. A partially completed ANOVA table is given. Fill in the missing entries, and test the relevant hypotheses using a .05 level of significance. (Give the answer to two decimal places.)

An experiment to compare the spreading rates of five different brands of yellow interior latex paint available in a particular area used 4 gallons (J = 4) of each paint. The sample average spreading rates (ft2/gal) for the five brands were x1. = 462.0, x2. = 512.8, x3. = 437.5, x4. = 469.3, and x5. = 532.1. The computed value of F was found to be significant at level α = 0.05. With MSE = 480.8, use Tukey's procedure to...

3. Suppose that a toy manufacturer developed 2 toys for the new season. Four different brands of batteries are uses in each of the 2 toys. The life of the toys with different batteries was analyzed. MINITAB results are presented. Two measurements were taken for each brand of batteries used on the 2 toys. Please: USE the P-Values, NOT F Tables. Each toy will be sold equipped with the specific battery which lasted the longest. What design should be used? Circle the one...
