A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 447 gram setting.
Mean =
n = 19
Since n < 30 , so we will use t test
Substitute the values :
t calculated = -0.830
degree of freedom = n-1 = 19-1 = 18
A level of significance=α=0.025
t critical = 2.093
t calculated < t critical
So, We failed to reject null hypothesis
Decision rule -0.830< 2.093 So, We failed to reject null hypothesis
The answer is 0, because you are adding an opposite to the original number, which always results in zero.
