if you could explain how to do this it would be great
Questiont Suppose the USGA wants to compare the mean distances associated with four different brands of golf balls when struck with a driver. Iron Bryon, the USGA's robotic golfer hits a random sample of 10 golf balls of each brand in a random sequence. The distance is recorded for each hit. A one-way analysis of variance was conducted (results below) to compare the mean distances of the four brands using a 5% level of significance Which multiple comparisons procedure is appropriate to conduct further testing?

here as p value is very less; further testing is required as test is significant.
as sample sizes are equal we need to do Tukey's HSD test cause Tukey Kramer test is for unequal sample size
option C is correct
