● Question 3 Only about 10% of all people can wiggle their ears. Is this percent different for millionaires? Of the 379 millionaires surveyed, 30 could wiggle their ears. What can be concluded at the a = 0.01 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: 80 F3 Ho: ? Select an answer ✓ H₁: ? Select an answer ✓ c. The test statistic ? ✓ = d. The p-value = e. The p-value is ? ✓ a f. Based on this, we should [Select an answer the null hypothesis. g. Thus, the final conclusion is that ... Submit Question (please enter a decimal) O The data suggest the population proportion is not significantly different from 10% at a = 0.01, so there is statistically insignificant evidence to conclude that the population proportion of millionaires who can wiggle their ears is different from 10%. $ (Please enter a decimal) O The data suggest the populaton proportion is significantly different from 10% at a = 0.01, so there is…
The hypothesis should revolve around one of the variables collected for all subjects. Your results section should describe the general course of one subject’s response from your individual analysis and then evaluate your hypothesis for a specific collective variable. Please explain this in plain english. I dont understand the instructions. Here is a reference of the subjects.
For each of the following hypotheses, identify which statistical test we could run in order to address the specific research question being asked. Your options are: z-Test, One-Sample t-Test, Independent-Samples t-Test, and Paired-Samples t-Test. Be sure to mention a bit about the research design to explain why you chose that specific test: 1) Do the Dodgers and Giants differ in the number of strikeouts they have per game? 2) Does our stats class differ from the national average in IQ? 3) Do people perform better or worse on a cognitive task after they eat cookies? 4) Do "only children" drive safer than other children with siblings? 5) Do people have more friends in college than they did in high school? 6) Do people experience higher levels of sadness or anger after a specific negative outcome?
The average wait time to get seated at a popular restaurant in the city on a Friday night is 13 minutes. Is the mean wait time greater for men who wear a tie? Wait times for 11 randomly selected men who were wearing a tie are shown below. Assume that the distribution of the population is normal. 12, 13, 13, 15, 13, 11, 14, 13, 15, 11, 15 What can be concluded at the the a = 0.01 level of significance level of significance?
7. The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject Ho when the level of significance is (a) α = 0.01, (b) x = 0.05, and (c) α = 0.10. P = 0.1176 (a) Do you reject or fail to reject Hå at the 0.01 level of significance? O A. Fail to reject Ho because the P-value, 0.1176, is greater than α = 0.01. Reject Hå because the P-value, 0.1176, is greater than α = 0.01. O B. O C. Fail to reject Ho because the P-value, 0.1176, is less than α = 0.01. O D. Reject Ho because the P-value, 0.1176, is less than α = = 0.01. (b) Do you reject or fail to reject Ho at the 0.05 level of significance? O A. Fail to reject Ho because the P-value, 0.1176, is less than α = 0.05. B. Fail to reject Ho because the P-value, 0.1176, is greater than α = 0.05. O C. Reject Ho because the P-value, 0.1176, is greater than α = = 0.05. D. Reject Ho because the P-value, 0.1176, is less than α = = 0.05. (c) Do you reject or fail to reject Ho at the 0.10 level of significance? O A. Reject…

I Need help with answering question 2 and 3. To conclude from the table given, there is a big difference in the hotels in the UK. The reason is that the P-Value is 0.5> so, therefore, we accept the value, therefore it's true that there is a big difference in the hotels in the UK. My question is, is my statement correct or am I wrong? This the information that given to me How likely is it that you would recommend <name hotel> to a friend or colleague on a scale from 0 (not likely) to 10 (most likely) What are the differences between hotels in UK: London, Birmingham, Leeds Thank you!
1 of 3 Unit 6 - Inference for Categorical Data: Proportions M&M Activity Name: Have you ever opened a bag of M&Ms and been surprised at the distribution of colors? We are going to investigate the different colors of M&Ms in a bag! Now, since I am not made of money, I can only afford for us to do a test based off of a fun-size pack. Now, you cannot EAT your candy!!! (right now...) Count the number of candies in your bag: _102 Fill in the chart with your information: Color Brown Red Yellow Orange Green Blue Count 14 11 10 37 11 19 Proportion 0.14 0.11 0.10 0.36 0.11 0.19 Looking at your data, you are going to test each claimed color given below. (Don't worry, we are not breaking rules – we will use the class data in a moment to actually conduct the test 0) Fill in the blank with , or * based on what you found in your bag. Brown: H.: p = 0.13 vs H,: p> 0.13 Red: H p-0.13 vs H.: p 0.15 Green: H p = 0.15 vs H,: p 0.13 H p- 0.20 vs H.: p< 0.20 St a p= 0.12 p=0.15 p=0.14 e Random - Random –…
