A researcher is interested in whether touch therapy improves the weight gain of pre-term infants.

1. What is the independent variable? The independent variable is the touch therapy being given.

2. What is the dependent variable? The dependent variable is the weight of the pre-term infants.

3. What is the research hypothesis? The research hypothesis is that the touch therapy increases the weight of the pre-term infants.

4. What is the null hypothesis? The null hypothesis is the touch therapy does not increase the weight of pre-term infants.

*5. If the researchers reject the null hypothesis, what is their conclusion?

*6. If the researchers fail to reject the null hypothesis, what is their conclusion?

*7. If the researchers make a Type I error, what does this mean?

*8. If the researchers make a Type II error, what does this mean?

I figured out the first 4 questions, just need the answers to the other 4 left

Answer #1

5) If null hyothesis is rejected:

conclusion: touch therapy does improve the weight gian of pre-term infants.

6) if null hypothesis is accepted:

conclusion: touch therapy does not improve the weight gian of pre-term infants.

7) if researcher make a Type I error.

Conclusion : the touch therapy does not improve the wieght gain of pre term ingants but after the touch therapy the weight gain of pre -term infants improved

8) type II

Conclusion: the pre- term infants wieght gain is improved after the touch therapy but the touch therapy does not improve the wieght gain of pre term infants.

A scientist has read that the mean birth weight, ?, of babies born at full term is 7.4 pounds. The scientist, believing that ? is different from this value, plans to perform a statistical test. She selects a random sample of birth weights of babies born at full term and finds the mean of the sample to be 7.1 pounds and the standard deviation to be 1.8 pounds. Based on this information answer the following questions What are the null...

I want to make a test whether the average weight of the students in the college is greater than 60 kg or not, i.e., we want to test the following hypothesis ?0 : ? = 60 vs ?1 : ? > 60. I will make the test using ?̅ as our test statistic and reject the null hypothesis if ?̅ ≥ 62. Take σ=10 and assume i will pick 50 students. 1) What is type 1 error that we commit...

Before a researcher tries to prove her alternative hypothesis, she wants to plan her experiment so that the resulting hypothesis test is "powerful". What does this mean? a. She wants to make sure that if the alternative hypothesis is true, there is a high probability that she will reject the null hypothesis. b. She wants to make sure that the probability of a type I error is small. c. She wants to make sure that if the null hypothesis is...

2. Sales at a fast-food restaurant average $6,000 per day. The restaurant decided to introduce an advertising campaign to increase daily sales. To determine the effectiveness of the advertising campaign, a sample of 49 days of sales were taken. They found that the average daily sales were $6,300 per day. From past history, the restaurant knew that its population standard deviation is about $1,000. If the level of significance is 0.05, have sales increased as a result of the advertising...

In a cognitive psychology experiment, the researcher is interested in whether encoding condition has an effect on memory for a list of words. She recruits 16 subjects to participate in the experiment. Each subject comes to the lab twice to be tested in two different encoding conditions and their memory performance scores are listed below. The researcher would like to leave the hypothesis non-directional without predicting which encoding condition would lead to better memory, and she sets the significance level...
