If we have a sample of size 100 with sample mean breaking strength of 1050 pounds from a population of rope with standard deviation 200 pounds and we wish to run a hypothesis test with this data to see if the population mean breaking strength differs from 1000 pounds, what is the significance of our data? 2P(Z>1.25) 2P(Z<2.5) NONE OF THE OTHERS 2P(Z>2.5) P(Z<2.5)
The body weight of a healthy 3-month-old colt should be about μ = 62 kg. (a) If you want to set up a statistical test to challenge the claim that μ = 62 kg, what would you use for the null hypothesis H0? μ > 62 kg μ < 62 kg μ = 62 kg μ ≠ 62 kg (b) In Nevada, there are many herds of wild horses. Suppose you want to test the claim that the average weight of a wild Nevada colt (3 months old) is less than 62 kg. What would you use for the alternate hypothesis H1? μ > 62 kg μ < 62 kg μ = 62 kg μ ≠ 62 kg (c) Suppose you want to test the claim that the average weight of such a wild colt is greater than 62 kg. What would you use for the alternate hypothesis? μ > 62 kg μ < 62 kg μ = 62 kg μ ≠ 62 kg
. The term sample usually refers to a sample that ___ - Consists of people with chemical dependency problems - Uses the same group of individuals with a before/after measurement - Requires a dependent variable for hypothesis testing - Is randomly selected from two dependent populations
If we have a sample of size 100 with sample mean breaking strength of 975 pounds from a population of rope with standard deviation 200 pounds and we wish to run a hypothesis test with this data to see if the population mean breaking strength is less than 1000 pounds, what is the P-Value of our data? 2P(Z<1.25) P(Z>1.25) P(Z>2.5) P(Z<1.25) NONE OF THE OTHERS
Test the null hypothesis H0 : β1 = β2 against the alternative H1 : β1 < β2 at 1% significance level.
Under what circumstances is the t statistic used instead of the Z score for a hypothesis test?
For the following cases, you may use either the P-value approach or the rejection region approach to present a full hypothesis test, including: Identifying the claim and H0 and Ha, Finding the appropriate standardized test statistic, Finding the P-value or the rejection region, Deciding whether to reject or fail to reject the null hypothesis, and Interpreting the decision in the context of the original claim. A scientist claims that pneumonia causes weight loss in mice. The table below shows weight, in grams, of six mice before infection with pneumonia and two days after infection. At α = 0.01, evaluate the scientist’s claim. Before After Mouse 1 19.8 18.4 Mouse 2 20.2 19.6 Mouse 3 19.9 19.1 Mouse 4 22.1 20.7 Mouse 5 23.4 22.2 Mouse 6 23.6 23.0
Given that the P-value for the hypothesis test is 0.000 when rounded to three decimal places, what do you conclude? What do the results indicate about the rule that women and children should be the first to be saved?
you have been hired by the San Antonio Spurs to analyze the 2005-2006 season. you will need to analyze the following three variables for EACH team: DRB - Number of Defensive Rebounds ORB – Number of Offensive Rebounds 3P – 3 point Field Goals Made Spurs- DRB- 2548 (31.1%) ORB- 851 ( 14.2%) 3P- 524 (.385%) Opponent - DRB- 2417 (29.5%) ORB- 886 (26%) 3P- 886 (.215%) Create a Null Hypothesis and Alternative Hypothesis based on the data above. The Hypothesis must be in written form and formula form. 2. Show the Cluster sample and explain how the data was collected and the data must represent a sample.
You are asked to test the null hypothesis at the .05 level of significance and you end up with z-observed being equal to -1.83. What would be the appropriate decision to make?
You complete a hypothesis test using alpha = .05 and based on the evidence from the sample, your decision is to fail to reject the null hypothesis. If the treatment actually does have an effect, which of the following is true?
When asked what it means for the result of a hypothesis test to be practically significant (or practically important), Tatum says this means that the P-value is small and the null hypothesis has been rejected. what is wrong about this?
