Use a = 0.05 and test to determine whether the distribution of lightning fatalities is the same for these two regions.
State the null and alternative hypotheses.
O H: Median number of lightning fatalities for Southern states - Median number of lightning fatalities for Western states s0
H: Median number of lightning fatalities for Southern states - Median number of lightning fatalities for Western states > 0
O H,: Median number of lightning fatalities for Southern states - Median number of lightning fatalities for Western states 2 o
H: Median number of lightning fatalities for Southern states - Median number of lightning fatalities for Western states < 0
O H,: The two populations of lightning fatalities are not identical.
H: The two populations of lightning fatalities are identical.
O H: The two populations of lightning fatalities are identical.
H: The two populations of lightning fatalities are not identical.
O H,: Median number of lightning fatalities for Southern states - Median number of lightning fatalities for Western states > 0
H: Median number of lightning fatalities for Southern states - Median number of lightning fatalities for Western states = 0
Find the value of the test statistic.
W =
Find the p-value. (Round your answer to four decimal places.)
p-value =
What is your conclusion?
O Reject H,. There is not sufficient evidence to conclude that the distribution of lightning fatalities is different for these two regions.
O Do not reject H,. There is sufficient evidence to conclude that the distribution of lightning fatalities is different for these two regions.
O Do not reject H. There is not sufficient evidence to conclude that the distribution of lightning fatalities is different for these two regions.
O Reject H. There is sufficient evidence to conclude that the distribution of lightning fatalities is different for these two regions.
