6. Use the sample you chose to perform a meaningful hypothesis test for the mean of the player weight. Include all the assumptions, identify clearly the null and alternate hypotheses, show the method used to test the hypothesis and write a clear conclusion    

                                                                                   

x=   

S=

n=

1. Assumptions/Claim: -10 pts-

2. Null Hypothesis H0: -10 pts-

Alternate Hypothesis H1:                                                                                                               

3. Method to Test the Hypothesis: -5 pts-

4. Conclusion: -10 pts-

Answer 1

n	100
x	202.75
S	21.79

The hypothesis being tested is:

H0: µ = 200

Ha: µ ≠ 200

Assumptions/Claim: µ ≠ 200

Method to Test the Hypothesis: t-test for one sample

200.000	hypothesized value
202.750	mean Data
21.791	std. dev.
2.179	std. error
100	n
99	df
1.262	t
.2099	p-value (two-tailed)

The p-value is 0.2099.

Since the p-value (0.2099) is greater than the significance level (0.05), we fail to reject the null hypothesis.

Therefore, we cannot conclude that µ ≠ 200.
