Answer:
y < - 6
Step-by-step explanation:
Given
- 2y > 12
Divide both sides by - 2, reversing the symbol as a result of dividing by a negative quantity.
y < - 6
Answer:
The requirements for the hypothesis test does satisfied the method for testing the claim that from two population proportions the rate of polio is less for children given the salk vaccine.
Step-by-step explanation:
The percentage of children in the treatment group was:
(201229/401974)*100 = 49.9%
The percentage of children given placebo was:
(200745/401974)*100 = 50.1%
The percentage of children that developed polio in the treatment group:
(33/200745)*100 = 0.0164%
The percentage of children that developed polio in the placebo group:
(115/201229)*100 = 0.0571%
The percentage difference between the two group:
((0.0571-0.0164)/0.0571) = 61.62%
Therefore:
The amount of children used for each group was almost divided into half of the total amount of children. The test revealed although very small percentages of the both group developed polio, 68.62% more children given placebo than the children that was given the salk vaccine. Therefore, the study shows that the rate of polio is less for children given the salk vaccine and the the hypthesis test is satisfied.

Answer:
Remaining cups = 10/3 cups
Step-by-step explanation:
Given:
Total amount of broccoli = 4 cup
Amount of broccoli used = 2/3 cup
Find:
Remaining cups
Computation:
Remaining cups = Total amount of broccoli - Amount of broccoli used
Remaining cups = 4 - 2/3
Remaining cups = (12-2) / 3
Remaining cups = 10/3 cups
