An amateur golfer wishes to determine if there is a difference between the drive distances of her two favorite drivers. (A driver is a specialized club for driving the golf ball down range.) She hits fourteen balls with driver A and 10 balls with driver B. The drive distances (in yards) for the trials are show below. Driver A 265 278 299 314 243 248 275 276 265 266 277 248 276 282 Driver B 233 220 217 239 235 245 261 194 272 233 Assume that the populations are approximately normal. Can you conclude that there is a difference in the mean drive distances for the two drivers? Use the α = 0.05 level of significance. Use 6-step p-value method.
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
