We frame the Hypothesis
To test the
we use t - Statistic; because the Population Standard Deviation
is unknown.
Where
Population Mean =
= 19.4
Sample Size = 36
Sample Mean =
= 17.6
Sample S.D =
= 5.4
Therefore
Therefore
Given Level of Significance = 5% = 0.05
p - Value:
The p-value is 0.053308
Therefore Option (b) is apt..
