14) The football coach at State University wishes to determine
if there is a decrease 14) in offensive production between the
first half and the second half of his team's recent games. The
table below shows the first-half and second-half offensive
production (measured in total yards gained per half) for the past
six games.
Game 123456 First half yards 147 65 140 72 149 84 Second half
yards 146 51 140 58 135 75 Can you conclude that the mean offensive
production in the first half differed from that of the second half?
i). State the null and alternative hypotheses. ii). Compute the
test statistic. iii). State a conclusion using the α = 0.10 level
of significance. Answer: i). H0: μd = 0, H1: μd > 0 ii). 3.205
iii). Reject H0. The mean offensive production appears to decrease
from the first half to the second half.
