Choose the appropriate concluding statement for the following hypothesis tests.
(a) You claim that the mean volume in all 12-ounce cans of Fizzy Pop soda is equal to 12 ounces. After analyzing the sample data and performing a hypothesis test, you fail to reject the null hypothesis.
The data supports the claim that the mean volume in all 12-ounce cans of Fizzy Pop is equal to 12 ounces.
There is not enough data to support the claim that the mean volume in all 12-ounce cans of Fizzy Pop is equal to 12 ounces.
There is enough data to justify rejection of the claim that the mean volume in all 12-ounce cans of Fizzy Pop is equal to 12 ounces.
There is not enough data to justify rejection of the claim that the mean volume in all 12-ounce cans of Fizzy Pop is equal to 12 ounces.
(b) You claim that the average speed of all cars traveling down a
certain stretch of highway is greater than 73 miles per hour (mph).
After analyzing the sample data and performing a hypothesis test,
you reject the null hypothesis.
The data supports the claim that the average speed is greater than 73 mph.
There is not enough data to support the claim that the average speed is greater than 73 mph.
There is enough data to justify rejection of the claim that the average speed is greater than 73 mph.
There is not enough data to justify rejection of the claim that the average speed is greater than 73 mph.
(c) You claim that the proportion of all cars traveling below the
speed limit is less than 45%. After analyzing the sample data and
performing a hypothesis test, you fail to reject the null
hypothesis.
The data supports the claim that the proportion of all cars traveling below the speed limit is less than 45%.
There is not enough data to support the claim that the proportion of all cars traveling below the speed limit is less than 45%.
There is enough data to justify rejection of the claim that the proportion of all cars traveling below the speed limit is less than 45%.
There is not enough data to justify rejection of the claim that the proportion of all cars traveling below the speed limit is less than 45%.

Hypothesis Testing - Setup: Suppose you want to test the claim that the mean volume in all 12-ounce cans of Fizzy Pop soda is less than 12 ounces. In a sample of 120 cans, you find the sample mean is 11.7 ounces. (a) What is the claim? μ < 12 μ > 12 μ = 12 μ = 11.7 (b) What does μ represent? the proportion of all cans with a volume < 12 ounces the mean volume of all...

Real Fruit Juice: A 32 ounce can of a popular fruit drink claims to contain 20% real fruit juice. Since this is a 32 ounce can, they are actually claiming that the can contains 6.4 ounces of real fruit juice. The consumer protection agency samples 56 such cans of this fruit drink. Of these, the mean volume of fruit juice is 6.32 with standard deviation of 0.23. Test the claim that the mean amount of real fruit juice in all...
