Answer:
The sampling distribution is, p = center = 0.043
The standard deviation of the sample, s = 6.0015×10⁻⁴
The shape is normal
Step-by-step explanation:
Here we have the standard deviation of a sample proportion, given by the following relation;
The center = p = 4.3% or 0.043
The shape is found by the value of n×p hence;
114250 × 0.043 = 4912.75 > 10 and
n(1 - p) = 114250 × (1 - 0.043) = 109337.25 also > 10 hence the shape is normal.
Row 1. Here you have the sum Meat+Beans+Rice, so the expression represent the the total price of all the food.
Row 2. Here you have the sum Beans+Rice. Since both foods are plants, the expression represent the total price of the foods from plants.
Row 3. Here you have the sum Meat+Beans+Rice again, so the expression represent the the total price of all the food.
Row 4. Here you have the sum Beans+Meat. Since beans and meat are both rich in proteins, the expression represent the total price of the foods rich in protein.
Row 5. Here you have the sum Meat+Rice. Since meat is not a plant and rice is not rich in protein, the correct answer is None of these.
Row 6. Here you have the sum Beans+Meat again just in a different order. Since beans and meat are both rich in proteins, the expression represent the total price of the foods rich in protein.
