Question

Hypothesis Testing - Conclusions: 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 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 less than 70 miles per hour (mph). After analyzing the sample data and performing a hypothesis test, you fail to reject the null hypothesis.

The data supports the claim that the average speed is less than 70 mph.

There is not enough data to support the claim that the average speed is less than 70 mph.

There is enough data to justify rejection of the claim that the average speed is less than 70 mph.

There is not enough data to justify rejection of the claim that the average speed is less than 70 mph.

(c) You claim that the proportion of all cars traveling below the speed limit is greater 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 greater than 45%.

There is not enough data to support the claim that the proportion of all cars traveling below the speed limit is greater than 45%.

There is enough data to justify rejection of the claim that the proportion of all cars traveling below the speed limit is greater 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 greater than 45%.
