You recently completed an experiment concerning the effects of carbs on happiness. One group of 11 people are assigned a high carb diet, another group of 11 people are assigned a moderate-high carb diet, another group of 11 people are assigned a moderate-low carb diet, and a final group of 11 people are assigned a low carb diet. If I find that I fail to reject the null hypothesis, what might my next step be? Group of answer choices Change my analysis and alpha to make the finding significant and then run post-hoc tests. 1. Run multiple dependent measures t-tests to see if there are any significant differences between particular groups 2. Run multiple independent samples t-tests to see if there are any significant differences between particular groups 3. Change my hypothesis to see if I can find something significant with a different hypothesis for this study 4. Run home and binge-watch Bridgerton because there is nothing else that should be done statistically
● 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…
10. Given the following null and alternative hypotheses: Ho : T, 2 T2 HA: TI < T2 together with the sample information: Sample 1 nį = 150 Sample 2 n2= 170 X2 = 80 X1 = 65 Test the hypotheses at 0.1 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…
3. For a z-test we get a test statistic of z=2.05. If our alternative hypothesis is "??:?>13Ha:μ>13", what Excel command would we use to compute the P-value? If our alternative hypothesis is "??:?<13Ha:μ<13", what Excel command would se use to compute the P-value?
Please show me the answer of question 3 and 4
Assume that, on the average, normal rhesus monkeys spend an mean of 60 minutes dreaming while sleeping at night (thus, μ = 60 minutes). Time spent dreaming is typically referred to as REM sleep (Rapid Eye Movement). You are interested in the effects a new dream-enhancing drug has on dreaming since an increase in the time spent dreaming while sleeping is thought to be a good thing in terms of getting a "restful" sleep. You want to pursue testing the drug in humans if there is any evidence that it significantly increases nightly dreaming time in these nonhuman primates. Ten rhesus monkeys are administered the drug in the morning and their dream time (in minutes) is monitored that night. The alternate hypothesis is: the drug will increase time spent dreaming, or the time in REM sleep. You obtain the following times (minutes) each monkey spent dreaming: 52, 69, 74, 60, 67, 65, 69, 55, 63, 68 Set alpha at a = .01, and complete step 4 of the hypothesis testing procedure, what decision should…

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.

Question 4 Suppose that, for some hypothesis test, a=0.05 and the P-value is computed to be 0.754. What is the appropriate conclusion? Reject the null hypothesis at a significance level of 0.05. It is not possible to make a conclusion based on the information provided. Fail to reject the null hypothesis at a significance level of 0.05. Accept the HO as the "P is low." Further testing is required before it can be determined if we should reject or fail to reject the null hypothesis at a significance level of 0.754.
