Answer:
Step-by-step explanation:
Information provided
n=100 represent the random sample taken
X=21 represent the number of bags overfilled
estimated proportion of overfilled bags
is the value that we want to test
z would represent the statistic
Hypothesis
We need to conduct a hypothesis in order to test if the true proportion of overfilled bags is higher than 0.15.:
Null hypothesis:
Alternative hypothesis:
The statistic for this case is:
(1)
And replacing the info given we got:
Answer:
106°
Step-by-step explanation:
The angle CAB is an inscribed angle of the arc mBC, so we have that:
mBC = 2*CAB
So we have that mBC = 2*37 = 74°
The segment AC is a diameter of the circle, so mAC = 180°
The ? angle is the arc mAB, which is the difference of mAC and mBC, so:
mAB = mAC - mBC = 180 - 74 = 106°
So the ? angle is 106°.
