A particular type of diet cola advertises that each can contains 12 ounces of the beverage. Each hour, a supervisor selects 10 cans at random, measures their contents, and computes a 95% confidence interval for the true mean volume. For one particular hour, the 95% confidence interval is 11.97 ounces to 12.05 ounces.
a. Does the confidence interval provide convincing evidence that the true mean volume is different than 12 ounces? Explain your answer.
b. Does the confidence interval provide convincing evidence that the true mean volume is 12 ounces? Explain your answer.
According to the given confidence interval, we have that:
a) Since 12 ounces is part of the confidence interval, the interval does not provide convincing evidence that the true mean volume is different than 12 ounces.
b) Since 12 ounces is part of the confidence interval, the interval provides convincing evidence that the true mean volume is 12 ounces.
What is the hypothesis tested?It is being tested if the true mean volume is different of 12 ounces, hence:
If the confidence interval contains 12 ounces, it provides convincing evidence that the true mean volume is 12 ounces.If the confidence interval does not contain 12 ounces, it provides convincing evidence that the true mean volume is not 12 ounces.In this problem, the interval is (11.97, 12.05), hence it provides convincing evidence that the true mean volume is 12 ounces, and basically, item a is False and item b is True.

Type the correct answer in the box. The solubility of calcium carbonate is 14. This rate means that 14 milligrams of calcium carbonate can dissolve in 1 liter of water. How much water would be required to fully dissolve 11 grams of calcium carbonate? Express your answer to the correct number of significant figures. One milligram is equal to 0. 001 grams. It would take liters of water to fully dissolve 11 grams of calcium carbonate.
Ratio compares two quantities. The amount of water that will be needed to dissolve 14 grams of calcium carbonate is 1000 liters.
Given to us
The solubility of calcium carbonate is 14.
We know that to dissolve 14 milligrams of calcium carbonate we will need 1 liter of water. therefore, the ratio of water and calcium carbonate can be written as,
[tex]\rm \dfrac{calcium\ carbonate}{water} = \dfrac{14\ milligram}{1\ liter}[/tex]
We need to find the amount of water needed to dissolve 14 grams of water, therefore, we will convert grams to milligrams,
1 gram = 1000 milligram
14 gram = 14,000 milligram
Using the same ratio,
[tex]\rm \dfrac{14,000\ milligram}{water} = \dfrac{14\ milligram}{1\ liter}[/tex]
[tex]\rm {water} = \dfrac{14000\ milligram \times 1\ liter}{14\ milligram}[/tex]
water = 1000 liters
Hence, the amount of water that will be needed to dissolve 14 grams of calcium carbonate is 1000 liters.

The total percent of decrease in price of the shares of Selena's stock which Selena first buys and then sold is 11.5 percent.
What is percentage decrease?Percentage decrease in a number is the ratio of total decrease in the original value of a number to the decreased value in the percentage form.
Given information-
The total stock buy by the Selena in $32.
The total stock sold by the Selena in $28.32.
As the total stock buy by the Selena in $32, and the total stock sold by the Selena in $28.32. Thus the total decrease in the price of stock is,
[tex]C_s=32-28.32\\C_s=3.68[/tex]
Thus the total decrease in the price of stock is $3.68.
As the cost price of the stock is $32 and the total decrease in the price of stock is $3.68. Thus the total percent of decrease in the price of the stock is,

Answer:
-84
Step-by-step explanation:
Let the number be x. Then we have,
[tex]\frac{x}{-7}[/tex] (the quotient of a number and -7)
[tex]\frac{x}{-7}-2[/tex] (decreased by 2)
[tex]\frac{x}{-7}-2=10[/tex] (is 10)
Now we can solve for x,:
[tex]\frac{x}{-7}-2=10[/tex]
[tex]\frac{x}{-7}=12[/tex]
[tex]x=-84[/tex]
So, the original number is -84
Answer:
-84

add 2 to each side to get:
[tex]\frac{n}{-7}[/tex] = 12
