1. State the null and alternative hypotheses that are being tested with the specified test.

(3 points)

H_o:

H_a:

2. Identify the test statistic and p-value you will use in this test of hypothesis (2 points)

Test Statistic: ____________           P-value: ___________

3. What assumption(s) is/are necessary for this analysis to be valid? Make sure you state your answer in the words of the problem (4 points)

4. Make a conclusion for the test of hypothesis conducted above. You should choose a.

(4 points)

Answer 1

a)

Null Hypothesis: H0 μ = 750

Alternative Hypothesis Ha: μ ≠ 750 ( 2 tailed)

b)Test Statistic: 10.9

p value = 0.000

c) ASSUMPTIONS

1. Test variable should be normally distributed

2. population sample size should be random sample

3. this Data is measurement data

4 cases of the sample is .independent

5. given that population mean is 750

d) conclusion

p value = 0 < all values of alpha or level of significance  

so Null hypothesis is rejected

Hence there is sufficient evidence to conclude that support the claim that there are different
