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
Answer:
L Pie - $7.50
B Pie - $4.50
Step-by-step explanation:
Let's create equations with the given things:
1. Two lemon meringue pies cost $3 less than four blueberry pies.
2L - $3 = 4B
2. Three lemon meringue pies cost #9 more than three blueberry pies.
3L = $9+3B
3. Let's solve these 2 equations
1. -3(-4B+2L=-3)
2. 2(-3B+3L=9)
3. Adding these 2 equations:
12B-6L = 9 ----(1)
-6B+6L= 18 ----(2)
(1) + (2) => 6B=27
B=$4.50
4. 2L = 4(4.50) - 3
L= $7.50
