In order to see which brand of golf balls is best (as measured by distance travelled), an experiment is set up where a mechanical driver hits 5 balls of each of 3 brands. Brand: (Callaway, Callaway, Callaway, Callaway, Callaway, Nike, Nike, Nike, Nike, Nike, Titleist, Titleist, Titleist, Titleist, Titleist) Distance: (296, 264, 269, 269, 277, 269, 269, 259, 274, 265, 298, 298, 310, 314, 293) We initally performed global F-test to this data at a = 0.05 and the result showed that there was a difference in mean distance between brands. Now, we want to perform pairwise t-test for each pair of brands adjusting with the Bonferroni methodology. What is the correct alpha level to be used for each pairwise t-test? O 0.2 O 0.05 O 0.15 O 0.025 O 0.0125 O 0.0167 0.0083
Solve the problem. Four brands of baseball bats were tested to determine which bat allowed hitters to hit a baseball farthest. Eight different batters were thrown 25 pitches while hitting with each of the four bats (assigned in random order). The average distance of the five longest hits using each bat is shown in the table below. The goal is to determine if the average hit distance differs for the four brands of baseball bats. Batter | Brand 1|Brand 2 | Brand 3 | Brand 4 315 1 307 300 275 310 317 305 285 3. 335 335 330 302 4. 325 328 320 300 300 305 295 270 345 350 340 310 7. 312 315 308 300 298 302 295 288 How should the data be analyzed?

Q23. A researcher records the number of words recalled by students presented with a list of words for one minute. In one group, students were presented with the list of words in color; in a second group, the same words were presented in black and white. An equal number of students were in each group. The results are reported in APA format below. Participants recalled significantly more words when the words were presented in color (M = 12.4 words) versus in black and white (M = 10.9 words), t(48) = 2.01, p < .05, η2 = .18. a. How many participants were in each group? = b. What was the decision regarding H0?(Select A or B) A. Reject H0B. Retain H0 Decision = c. What was the value of the effect size? = d. Is this a trival, small, medium, or large effect? = (see Table 8.4, p. 239)
