Agolf pro wanted to compare two types of golf clubs. one type is graphite-shafted and the other is steel-shafted. it is a common belief that graphite shafts give more distance. this belief is tested by having 10 golfers hit one ball with each type of club and then determining the distance that the ball traveled. a coin flip was used to determine which type of club each player would hit with first. results indicated that there was no difference in the two types of club. complete parts (a) through () below. (a) what type of experimental design is this? o matched-pairs design o case-control study o randomized block design o completely randomized design (b) what is the response variable in this study? o the distance o the coin flip o the types of club o the golfers (c) what is the factor that is set to predetermined levels? what is the treatment? oa. o b. o c. the factor is the golfers. the treatments are the 10 different golfers. the factor is the type of club. te treatments are graphite-shafted and steel-shafted. the factor is the distance. the treatments are graphite-shafted and steel-shafted d. the factor is the coin flip. the treatments are heads and tails. (d) identify the experimental units. choose the correct answer below. o the types of club o the coin flip o the distance o the golfers
