A large sports team claims that, on average, 14500 fans attend a game at their stadium. A company that just invested in the stadium wants to perform a test to determine whether or not more fans attend. They take a random sample of 19 past games and find a mean attendance of 16800 fans. They know the standard deviation for every game is 3550 fans. Perform the test at a 4% level of significance. Assume the population for game attendance is normally distributed. a. Check all of the requirements that are satisfied. random the a distribution is normal since n > 30 the a distribution is normal since the x distribution is normal the p distribution is normal since np > 5 and nq > 5 b.

Question
f. Find the test statistic. Write the result below,
and be sure to round your final answer to two
decimal places.
g. Find the p-value. Enter your answer as a
decimal (not a percentage) and round to 4
decimal places.
h. Should you reject or not reject the null
hypothesis?
O reject the null hypothesis Ho, since p-
value < a
fail to reject the null hypothesis Ho,
since p-value > a
reject the null hypothesis Ho, since p-
value > a
fail to reject the null hypothesis Họ,
since p-value < a
i. Select the statement below that best
represents the interpretation.
There is sufficient evidence to support
the claim that more than an average of
14500 fans attend the games.
There is not sufficient evidence to
support the claim that more than an
average of 14500 fans attend the games.
| The sample data support the claim that
more than an average of 14500 fans
attend the games.
We accept that 14500 fans attend the
games on average.
