Answer:
a.H0: μ =530mL vs. Ha: μ > 530mL
Step-by-step explanation:
-A hypothesis test will be used to provide evidence that the median is more or equal to the stated median value.
#In a normally distributed population, the mean=mode=median:
-The null hypothesis states that the median is equal to the stated value:
-The alternative hypothesis provides evidence that the median value is greater than the stated value:
Hence, the correct hypotheses are H0: μ =530mL vs. Ha: μ > 530mL
Your equation has no solution.

Answer:
Mean, E(x) = 0.17
Variance, V(x) = 0.12
Step-by-step explanation:
90% contains no defective bulbs, P(X=0) = 0.9
5% contain one defective bulbs, P(X=1) = 0.05
3% contain two defective bulbs, P(X=2) = 0.03
2% contain three defective bulbs, P(X=3) = 0.02
The mean for the number of defective bulbs:
Variance for the defective bulbs:
V(x) = 0.29 - 0.17
V(x) = 0.12
Answer:
greater than ............
To make any meaningful calculations here, you'll have to think about how the area of each room is calculated, as well as to invent how much per square yard the various types of carpeting cost.
Note that the cost of carpeting one room would be (room area)(carpet cost per square foot).
