You go out and randomly select 10 people and force them to eat a lot of tumeric. One week later, you give them an inflammation test. You find the following inflammation values for each person: 2,3,0,-1,1,2,1,-1,2,2.

a. What is the mean of your sample?

I am telling you that sigma=2. b. If you assume the Null hypothesis is true, then what is the distribution your sample mean is drawn from?

c. Compute the corresponding Z-score for your mean.

d. What is the probability that the Null Hypothesis is true (p-value)?

e. Based on your alpha, should you reject the Null Hypothesis?

These same researchers want to test their hypothesis again. This time they randomly select 54 people, show them the film, and give them an attitude questionnaire. The mean score on the attitude test for these 54 people is 72. The score for people in general on this test is 75, with a standard deviation of 12. Using the steps of hypothesis testing and the 5% significance level, carry out a Z test to see if viewing the film changes people’s...

You conduct a survey of UNR undergraduate students regarding sleeping habits. In your sample, 39 out of the 96 people you survey go to sleep before midnight. (Assume that the 50% of the general population go to sleep before midnight.) a) Calculate a 90% confidence interval for the true proportion of UNR undergraduates who go to sleep before midnight. Perform a two-sided hypothesis test at alpha=0.10. b) If the true proportion of UNR undergraduates who go to sleep before midnight...

Survey 40 people and ask them this question: “How many days a week do you typically exercise?” You calculated your average for the results, and standard deviation and standard error. The following are your results: Average: 4.8625 Standard Deviation: 1.1602 Standard Error: 0.1834 You then ask a friend what they think the average value is for a person who typically exercises during the week. Your friend claims the average to be 4. 1. What are the appropriate null and alternative...

Suppose you ran 50 separate simulations. Each of these simulations represent a week (7 days) of working with a molding machine. During each simulation, the average number of the machine's failures per day was recorded. You observed that the mean of all of your sample means follows a normal distribution with a standard deviation of 25 that is, ~N(M, 25). Later you decided to run a hypothesis testing on the population mean with the assumptions below and an alpha =...

One-sample t: Suppose you are a big fan of world cup soccer and want to know if the soccer ball that is going to be used in the next world cup is a different weight than the balls used in the last world cup. a. Would you formulate this as a one or two sided hypothesis test? Suppose the average weight of the ball used in the last world cup was 500g. b. State the null and alternative hypotheses for...

Think about a population mean that you may be interested in and propose a hypothesis test problem for this parameter. Gather appropriate data and post your problem, Later, respond to your own post with your own solution. For example, you may believe that the population mean number of times that adults go out for dinner each week is less than 1.5. Your data could be that you spoke with 7 people and found that they went out 2, 0, 1,...

Multiple Choice: How often do you go out dancing? This question was asked by a professional survey group on behalf of the National Arts Survey. A random sample of 95 single men showed that 24% went out dancing occasionally. Another random sample of 92 single women showed that 21% went out dancing occasionally. Is the proportion of single men who go out dancing occasionally higher than the proportion of single women? Use a 5% level of significance. If men are...

1. A social researcher wants to test the hypothesis that people who drink a lot while bowling have higher scores than people who do not drink while they bowl. The researcher studies 50 drinking bowlers and 50 non-drinking bowlers. The average score for drinking bowlers was 142 with a standard deviation of 7.45. The average score for non-drinking bowlers was 134 with a standard deviation of 6.81. In words: What are your conclusions about the null hypothesis? 2. A social...
