Do left handed starting pitchers pitch the same number of

pitchers? A researcher looked at eleven randomly selected
left handed starting pitchers' games and ten randomly
selected right handed pitchers' games. The table below

Assume that both populations follow a normal distribution.
What can be concluded at the the a = 0.10 level of

e. Based on this, we should Select an answer the null
hypothesis.
f. Thus, the final conclusion is that ...
The results are statistically significant at a =
0.10, so there is sufficient evidence to
conclude that the mean innings per game for
the eleven left handed starting pitchers that
were looked at is not the same as the mean
innings per game for the ten right handed
starting pitchers that were looked at.
The results are statistically insignificant at a =
0.10, so there is statistically significant
evidence to conclude that the population mean
innings per game for left handed starting
pitchers is equal to the population mean innings
per game for right handed starting pitchers.
The results are statistically insignificant at a =
0.10, so there is insufficient evidence to
conclude that the population mean innings per
game for left handed starting pitchers is not
the same as the population mean innings per
game for right handed starting pitchers.
The results are statistically significant at a =

g. Interpret the p-value in the context of the study.
O There is a 42.96% chance that the mean
innings per game for the 10 lefties differs by at
least 0.4 innings per game compared to the 9
righties.
