Assignment 5
1. Consider the meteorological dataset used in Example 4.1. Test whether 1980 and 1982 were
atypical years with respect to the average maximum temperature. Use the same test value
as in Example 1.
YEAR 1980
Null Hypothesis: (𝐻
0
): 𝜇 = 37.5° Alternative Hypothesis (𝐻
1
) : 𝜇 ≠ 37.5°
Test:
t-test, two-tailed
Result:
Decision:
Since the p-value = 0.8927 > 0.05, we fail to reject the null hypothesis, the test is not significant.
Conclusion:
There is not enough evidence to prove that the year 1980 was atypical year with respect to the
average maximum temperature.

YEAR 1982
Null Hypothesis: (𝐻
0
): 𝜇 = 37.5° Alternative Hypothesis (𝐻
1
) : 𝜇 ≠ 37.5°
Test:
t-test, two-tailed
Result:
Decision:
Since the p-value = 0.897 > 0.05, we fail to reject the null hypothesis, the test is not significant.
Conclusion:
There is not enough evidence to prove that the year 1982 was atypical year with respect to the
average maximum temperature.

2. Consider the Programming dataset containing student scores during the period 1986-88.
