e. The test-statistic for this data
(Please
show your answer to three decimal places.)
f. The p-value for this sample =
(Please show
your answer to four decimal places.)
g. The p-value is Select an answer
h. Based on this, we should Select an answer
i. Thus, the final conclusion is...
There is sufficient evidence to conclude that
the distribution of die rolls is uniform.
There is sufficient evidence to conclude that
the distribution of die rolls is not uniform.
There is insufficient evidence to conclude that
the distribution of die rolls is not uniform.
There is insufficient evidence to conclude that
the die rolls are dependent.
O There is sufficient evidence to conclude that
the die rolls are dependent.
