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 less than 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 less than 12 ounces. There is not enough data to support the claim that the mean volume in all 12-ounce cans of Fizzy Pop is less than 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 less than 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 less than 12 ounces.


(b) You claim that the average speed of all cars traveling down a certain stretch of highway is equal to 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 equal to 73 mph. There is not enough data to support the claim that the average speed is equal to 73 mph.     There is enough data to justify rejection of the claim that the average speed is equal to 73 mph. There is not enough data to justify rejection of the claim that the average speed is equal to 73 mph.


(c) You claim that the proportion of all cars traveling below the speed limit is greater than 35%. After analyzing the sample data and performing a hypothesis test, you reject the null hypothesis.

The data supports the claim that the proportion of all cars traveling below the speed limit is greater than 35%. There is not enough data to support the claim that the proportion of all cars traveling below the speed limit is greater than 35%.     There is enough data to justify rejection of the claim that the proportion of all cars traveling below the speed limit is greater than 35%. 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 35%.

On your first day on the job, your boss asks you to conduct a hypothesis test about the mean dwell time of a new type of UAV. Before you arrived, an experiment was conducted on n= 5 UAVs (all of the new type) resulting in a sample mean dwell time of y-bar= 9.4 ℎours. The goal is to conclusively demonstrate, if possible, that the data supports the manufacturer’s claim that the mean dwell time is greater than 10 hours. Given...

Suppose you work for Fender Guitar Company and you are responsible for testing the integrity of a new formulation of guitar strings. To perform your analysis, you randomly select 51 'high E' strings and put them into a machine that simulates string plucking thousands of times per minute. You record the number of plucks each string takes before failure and compile a dataset. You find that the average number of plucks is 6,398 with a standard deviation of 286.12. A...
