You are a consumer psychologist interested in holiday spending. A national census reports that the American family spent an average of u = $81 for Halloween candy and costumes last year. A sample of N = 16 families this year produced a mean of $85 with s = 20. What is the critical t Based upon your obtained t and critical t, can you reject the null? Yes No Not enough info
Suppose the study described in the previous question was conducted by a colleague. He tells you that based on a chi-square distribution with 2 degrees of freedom, his p-value was 0.11, and he concludes that the proportions are not the same across health status categories. Do you agree with his conclusion? Yes, by rejecting the null hypothesis, it does appear that the proportions are not the same. Yes. He should have not rejected the null hypothesis and concluded that they do not appear to be related. Yes. a p-value > 0.05 always indicates that variables are related regardless of the test conducted
Based on your confidence interval from the previous problem, can you conclude that the mean permeability coefficient at 60∘60∘C differs from that at 61∘61∘C at the 0.05 level of significance? A. Yes, because the 95% confidence interval includes 0 B. No, because the 95% confidence interval includes 0 C. Yes, because the 95% confidence interval does not include 0 D. No, because the 95% confidence interval does not include 0 E. It is impossible answer this question only using the 95% confidence interval.

People end up tossing 12% of what they buy at the grocery store (Reader's Digest, March 2009). Assume this is the true population proportion and that you plan to take a sample survey of 540 grocery shoppers to further investigate their behavior. Answer questions 8-10.
A medical research team at the university is investigating the effectiveness of a new medical treatment for a rare disease. Data indicates that under the current treatment, patients have a mean white blood cell count of 23 cells/cc (cubic centimeter). This distribution is understood to be normally distributed, but the population standard deviation is not known. The new treatment will only be deemed effective if it significantly increases the patient’s white blood cell count above 23 cells/cc. The team has applied the treatment to a random sample of 10 patients. They have reported the following blood cell counts: 21, 25, 18, 24, 19, 25, 22, 20, 27, 25 At α = .01, is the new treatment effective?
A certain magazine stated that the mean time for a Ford Mustang to go from 0 to 60 miles per hour is 4.1 seconds. (a) If you want to set up a statistical test to challenge the claim of 4.1 seconds, what would you use for the null hypothesis? 04.1 O = 4.1 (b) The town of Leadville, Colorado, has an elevation over 10,000 feet. Suppose you wanted to test the claim that the average time to accelerate from 0 to 60 miles per hour is longer Leadville (because of less oxygen). What would you use for the alternate hypothesis? OH 4.1 OM 4.1 O = 4.1 (c) Suppose you made an engine modification and you think the average time to accelerate from 0 to 60 miles per hour is reduced. What would you use for the alternate hypothesis? OH> 4.1 O μ< 4.1 OH 4.1. (d) For each of the tests in parts (b) and (c), would the P-value area be on the left, on the right, or on both sides of the mean? O left; both O right; left O left; right O both; left
Solve B to D
You want to obtain a sample to estimate a population mean. Based on previous evidence, you believe the population standard deviation is approximately o = 23.8. You would like to be 98% confident that your estimate is within 2.5 of the true population mean. How large of a sample size is required? Do not round mid-calculation. However, you are encouraged to use a critical value accurate to three decimal places – this is important for the system to be able to give hints for incorrect answers.
True or false: if we want to know whether two qualitative variables with many possible outcomes are related, this is impossible to test because statistics deals with quantitative data only. a. False: we can just arbitrarily assign numbers to those outcomes and do regression b. True: we cannot safely do regression on qualitative variables in any circumstances c. False: we can conduct a chi-square test on the independence of these two variables d. True: in general, we don’t use qualitative variables in statistics
In each of the following scenarios there is something wrong. Describe what is wrong and give a reason for you the answer. 1) If you multiply a random vriable by 10, then the mean is multiplied by 10 and the variance is multiplied by 10. 2) When finding then mean of the sum of two random variables, you need to know the correlation between them.
The standard deviation in the pressure required to open a certain valve is known to be o = 0.8 psi. Due to changes in the manufacturing process, the quality-control manager feels that the pressure variability has been reduced. (a) State the null and alternative hypotheses in words. (b) State the null and alternative hypotheses symbolically. (c) Explain what it would mean to make a Type I error. (d) Explain what it would mean to make a Type II error. (a) State the null hypothesis in words. Choose the correct answer below. A. The standard deviation in the pressure required to open any valve is 0.8 psi. B. The standard deviation in the pressure required to open a certain valve is different from 0.8 psi. C. The standard deviation in the pressure required to open a certain valve is greater than 0.8 psi.
