Use 5% level of significance. At the fifth hockey game of the season at a certain arena, 200 people were selected at random and asked as to how many of the previous four games they had attended. The results are given in the table below.
| Number of games previously attended | Number of People |
| 0 | 33 |
| 1 | 67 |
| 2 | 66 |
| 3 | 15 |
| 4 | 19 |
Test the hypothesis that these 200 observed values can be regarded as a random sample from a binomial distribution,where ‘θ’ is the unknown parameter representing the probability of success that a person will attend a game.

The probability that a certain hockey team will win any given
game is 0.3628 based on their 13 year win history of 377 wins out
of 1039 games played (as of a certain date). Their schedule for
November contains 12 games. Let X = number of games won in
November. Find the probability that the hockey team wins at least 7
games in November. (Round your answer to four decimal places.)
Please use TI-84 calculator not excel.

Use a 5% significance level.
In a large city, 200 persons were selected
at random and each person was asked how many tickets he purchased
that week in the state lottery. The results are given in the
following table. Suppose that among
the 7 persons who had
purchased five or more
tickets, 3 persons had purchased exactly five
tickets, 2 persons had purchased six
tickets, 1 had purchased seven tickets,
and 1 had purchased ten tickets. Test the
hypothesis that these 200 observations form a
random sample from a Poisson
distribution.

A hypothesis test with a 5% level of significance is designed to
test the claim that the mean weight of a new breed of chickens is
greater than 6.00 pounds. A sample of 81 chickens is obtained and
their mean weight is 6.20 pounds with a sample standard deviation
of 0.50 pounds. No information is available concerning the standard
deviation of the whole population of the new breed. What is the
critical value (from Table A-3) and the test statistic...

At the 5% significance level, test the claim that the variance
in wait times for a call center is 100 square minutes. A simple
random sample of 9 call center calls found that the mean wait time
was 97.7 minutes with a standard deviation of 11.3 minutes. Assume
the population is normally distributed.

test you are using, and why.
