MS betweenA researcher would like to know if a vegan diet will lower cholesterol. A sample of n = 9 adults is obtained, and each has their cholesterol levels measured. Each participant then goes on a strict vegan diet for the next 45 days and cholesterol levels are measured again after that. Average total cholesterol dropped by MD = 14 points after the vegan diet with SS = 1152 for the difference scores. Which of the following is the best statement of HO? What is the critical value of t for two tailed, alpha 0.05? What is the sample variance? Report a number to one decimal. What is the sample standard deviation? Report to one decimal What is the value for the estimated standard error? Report to one decimal. What if the observed t value from the example above? Answer to two decimals. How many degrees of freedom are in the current study? Report a whole number no decimals. True or false. Based on your calculations, the correct decision would be fail to Reject H0.The personality trait of "Conscientiousness" (someone who is organized, responsible, and can control their impulses) has μ = 120 and σ =9. Test whether ARC students (n = 9, M = 126) differ on Conscientiousness. α = .05. Does the z score for the sample mean lie in the critical region (beyond the critical boundary)?
- A random sample of 100 students at a high school was asked whether they would ask their father or mother for help with a financial problem. A second sample of 100 different students was asked the same question regarding a dating problem. If 43 students in the first sample and 47 students in the second sample replied that they turned to their mother rather than their father for help, test the hypothesis of no difference in the proportions. Use α = 0.02. Identify the critical value(s). 2.33 ±2.33±2.33 ±2.05±2.05 2.05A manufacturer wants to increase the shelf life of a line of cake mixes. Past records indicate that the average shelf life of the mix is 231 days. After a revised mix has been developed, a sample of nine boxes of cake mix gave these shelf lives (in days): 230,233, 235, 236, 233, 240, 240, 241, and 237. Using α = 0.025, has the shelf life of the cake mix increased? Multiple Choice Yes, because computed t is greater than the critical value. Yes, because computed t is less than the critical value. No, because computed t lies in the region of acceptance. No, because 236.11 is quite close to 231.Your company manufactures plastic wrap for food storage. The tear resistance of the wrap, denoted by X, must be controlled so that the wrap can be torn off the roll without too much effort but it does not tear too easily when in use. In a series of tests (see data table below), 15 rolls of wrap are made under carefully controlled conditions and the tear resistance of each rool is measured. The results are used as the basis of a quality assurance specification. If X for a subsequently produced roll falls more than two standard deviations away from the test period average, the process is declared out of specification and production is suspended for routine maintenance.

You recorded the mileage of 10 independent cars with a gallon of said gasoline and obtained an average of 23.7mi. You want to determine if this is enough evidence to say that the brand is overestimating. Given a critical value of t = 0.822 and a significance level of 0.10, should we reject the H0?

In a random sample of 260 people from that country, 78 have changed jobs in the past three years. At α=0.05, is there enough evidence to support the center's claim? Complete parts (a) through (e) below. a. Identify the claim and state HO and Ha. b. find the critical value(s) and identify the rejection region(s) c. Find the standardized test statistic z. d. Decide whether to reject or fail to reject the null hypothesis and interpret the decision in the context of the original claim.For this study, we should use The null and alternative hypotheses would be: z-test for a population proportion or t-test for a population mean Ho: (p or u) (please enter a decimal) H1: (p or u) (Please enter a decimal) The test statistic z = (please show your answer to 3 decimal places.) The critical value = (Please show your answer to 3 decimal places.) The test statistic (is or is not) in the rejection region.
