A sample statistic , such as x bar, that estimates the value of the corresponding population parameter is known as a control chart.
Answer:

Step-by-step explanation:
-A hypothesis is a claim of evidence and is used in making statistical decisions during experiments/ research.
-Given that 10% of the entire shipment is bruised.
-the null hypothesis states that the proportion is equal to the stated value:

-The alternative states that the null hypothesis is not correct:

Answer:
V = 23π/6
Step-by-step explanation:
V = 2π ∫ [a to b] (r * h) dx
y = −x² + 23x − 132
y = −(x² − 23x + 132)
y = −(x − 11) (x − 12)
Parabola intersects x-axis (line y = 0) at x = 11 and x = 12 ----> a = 11, b = 12
r = x
h = −x² + 23x − 132
V = 2π ∫ [11 to 12] x (−x² + 23x − 132) dx
V = 23π/6
