Question
Choose the appropriate concluding statement for the following hypothesis tests
1. 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.
a)The data supports the claim that the mean volume in all 12-ounce cans of Fizzy Pop is equal to 12 ounces.
b)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.
c)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.
d)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.
2. You claim that the average speed of all cars traveling down a certain stretch of highway is less than 74 miles per hour (mph). After analyzing the sample data and performing a hypothesis test, you fail to reject the null hypothesis.
a)The data supports the claim that the average speed is less than 74 mph.
b)There is not enough data to support the claim that the average speed is less than 74 mph.
c)There is enough data to justify rejection of the claim that the average speed is less than 74 mph.
d)There is not enough data to justify rejection of the claim that the average speed is less than 74 mph.
3. 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.
a)The data supports the claim that the proportion of all cars traveling below the speed limit is greater than 35%.
b)There is not enough data to support the claim that the proportion of all cars traveling below the speed limit is greater than 35%.
c)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%.
d)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%.
Explanation / Answer
1 a) Rejection of null hypothesis means there is sufficient sample evidence to conclude that mean volum eof all 12 ounce soda cans of Fizzy Pop is equal to 12 ounce.
2. b) Fail to reject null hypothesis means there is not sufficient sample evidence to support the claim.
3. a) Rejection of null hypothesis asserts the claim as made in alternative hypothesis.
