Answer: There is sufficient evidence to support the claim that the bags are under-filled.
Step-by-step explanation:
Since we have given that
Sample mean = 411
Standard deviation = 20
n = 9
So, the test statistic value is given by
At 0.025 level of significance,
critical value z = -2.306
since -2.306<-1.05
so, we will reject the null hypothesis.
Yes, there is sufficient evidence to support the claim that the bags are underfilled.
6.66 × 10 = 66.6 is the answer.
-60/4 > 32/(-2)

-60/4=-15
32/-2=-16
