Determine if the following statement is a null hypothesis or an alternative hypothesis.
“The average amount of time that all Americans spend exercising is 15 minutes a day.”
Determine if the following statement is a null hypothesis or an alternative hypothesis. “The average amount...
dentify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. The typical drying time for a new finger nail polish is 4.5 minutes on average. A random sample of 16 painted fingers produced a sample with a mean of 4.1 and a standard deviation of 0.8 minutes. Complete the appropriate test to determine if this drying time is statistically less time. (Use a 4 or 5 step method)
1. State the null hypothesis, 0 , and the alternative hypothesis. 1 , for the following statement: Americans have a mean paid vacation each year of three weeks. a. 0:x-bar=3;1:x-bar≠3 b. 0: =3;1: ≠3 c. 0:x-bar≠3;1:x-bar =3 d. 0: ≠3;1: =3
Examine the given statement, then identify whether the statement is a null hypothesis, an alternative hypothesis or neither. The mean μ = 5.5. PS: It's not Alternative hypothesis Question options: A) Neither B) Null hypothesis
Which of the following results in the null hypothesis μ=38 and alternative hypothesis μ<38? Select the correct answer below: a. A fitness center claims that the mean amount of time that a person spends at the gym per visit is at most 38 minutes. b. A fitness center claims that the mean amount of time that a person spends at the gym per visit is fewer than 38 minutes. c. A fitness center claims that the mean amount of time...

A professor refutes the claim that the average student spends three hours studying for the midterm exam. Which hypothesis is...
1. state the hypothesis and identify the claim with the correct hypothesis. Also one or two tailed test? 2. Compute the test value 3. Find the P-value 4. Make the decision to reject or not reject the null hypothesis 5. Summarize the results Question 4 of 10 (1 point) View problem in a pop-up Men spend an average of 29 minutes per day on weekends and holidays exercising and playing sports. They spend an average of 23 minutes per day...
Determine whether the claim stated below represents the null hypothesis or the alternative hypothesis. If a hypothesis test is performed, how should you interpret a decision that (a) rejects the null hypothesis or (b) fails to reject the null hypothesis? A researcher claims that the standard deviation of the life of a certain type of lawn mower is at most 3.8 years. Does the claim represent the null hypothesis or the alternative hypothesis? Since the claim does not contain a...
