Because the t value you found is _______ , you decide to ________ the null hypothesis. (Note that this conclusion is also supported by the significance reported by SPSS.) Group of answer choices in the critical region, reject in the critical region, accept NOT in the critical region, accept NOT in the critical region, reject

The data below are from a sensory deprivation study looking at hearing threshold before and after one hour in a sensory deprivation chamber. Seven subjects had their hearing checked both before and after they were in a dark, silent chamber. Hearing threshold is the minimum sound level you can detect. Test the hypothesis that hearing should be more sensitive (thus lower numbers) after sensory deprivation compared with before (use alpha = .05). BEFORE: 11, 34, 18, 33, 35, 22, 35 AFTER: 13, 31, 18, 29, 32, 20, 28 What is the design of this study? What is the independent variable? What is the dependent variable? n = people Is the hypothesis one-tailed or two-tailed? State the Hypotheses in symbols and words: in words: Hị: in words: Create an Excel data file organized by rows. Each row is a participant. Variables – Before, After Open this dataset in JASP. To test the experimenters' hypothesis, perform a related samples t-test by selecting T-Tests > Classical > Paired Samples t-test (Student…

How is the hatching of water python eggs influenced by the temperature of the snake's nest? Researchers randomly assigned newly laid eggs to one of three water temperatures: hot, neutral, or cold. Hot duplicates the extra warmth provided by the mother python, and cold duplicates the absence of the mother. The table shows the result of the experiment. The researchers will use a chi-square test for homogeneity to analyze the findings. Hatching status Yes No Total Cold 16 11 27 Water Temperature Neutral Hot 38 75 18 56 104 Total 129 58 187 Which of the following is false? All of the conditions are met for conducting a chi- square test for homogeneity. The data came from 3 groups in a randomized experiment. All expected counts are at least 5. The 10% condition is met. The 10% condition is not needed because the eggs were not randomly selected from the population. Incorrect

CSLO 4, 5, 6, 9, 10 Unit 7 DQ: What's Worse a Type I or Type II Error? A doctor is considering prescribing a new medication that helps lower blood sugar for diabetes; he claims the medication is not toxic. You will test the medication to see if it is toxic. Set up the null and alternative hypotheses. Explain what the Type I and Type II errors would be in the situation.

6- Hi Wonderful Bartleby Team (Thanks for all the help I do really aprecciate all you guys do) I need help with this exercise from stats. Thanks in advance

I did questions that I already understood I just need help with question b and question C

I need #4 answered

a=0.01, z=2.79. h a: u1>u2 What is the critical Z Value? What is the decision making for this hypothesis test?   A is the positive critical value for this question, what is/are the possible critical region(s) for this hypothesis test?

MORE BENEFITS OF EATING ORGANIC Using specific data, we find a significant difference in the proportion of fruit flies surviving after 13 days between those eating organic potatoes and those eating conventional (not organic) potatoes. This exercise asks you to conduct a hypothesis test using additional data. In this case, we are testing where p, and p, represent the proportion of fruit flies alive at the end of the given time frame of those eating organic food and those eating conventional food, respectively. Use a 5 % significance level. Effect of Organic Soybeans After 5 Days After 5 days, the proportion of fruit flies eating organic soybeans still alive is 0.9, while the proportion still alive eating conventional soybeans is 0.83. The standard error for the difference in proportions is 0.023. What is the value of the test statistic? Round your answer to two decimal places. What is the p-value? Round your answer to three decimal places. p-value= i ! What is the conclusion? Ho: Po Pe…
