Using a long rod that has length m, you are goingto lay out a square plot in which the length of eachside is m. Thus the area of the plot will be m2.However, you do not know the value of m, soyou decide to make n independent measurementsX1, X2,... Xn of the length. Assume that each Xihas mean m (unbiased measurements) and variance s2.a. Show that X2 is not an unbiased estimatorfor m2. [Hint: For any rv Y, E(Y2) ¼V(Y) + [E(Y)]2. Apply this with Y ¼ X.]b. For what value of k is the estimator X2 - kS2unbiased for m2? [Hint: Compute E(X2 - kS2).]
How many levels or categories does a study have if using a goodness of fit test and reporting a df=2 A study using the chi-square test of independence has 4 categories of one variables and 2 categories for its other variable. What are the degrees of freedom for the study? If a chi-square test of Independence ends in a non-significant result it means that the variables depend on each other. True False
comparison of the precisions of two machines developed for extracting juice from oranges is to be made using the following data. Is there sufficient evidence to indicate that there is a difference in the precision of the two machines at the 5% level of significance? Machine A Machine B s2 = 1.4 ounces2 s2 = 3.1 ounces2 n=25 n=20
Having the variation data regression line r=0.931 and the calculated coefficient of determination of 0.867.. And explained variation of the data of 86.7%.. About the unexplained variation? [ ] % of the variation is unexplained and is due to other factors or to sampling error. (Round to one decimal place as needed.)
The director of research and development is testing a new drug. She wants to know if there is evidence at the 0.02 level that the drug stays in the system for more than 312 minutes. For a sample of 69 patients, the mean time the drug stayed in the system was 319 minutes. Assume the variance is known to be 400. Enter the decision rule. Reject Ho if z >_______
True or False If the comparison wise type I error is set at 0.05, then the experiment wise type I error is equal to or Greater than 0.05
Getting an adequate amount of sleep can improve a variety of physiological functions, and it is known that the average number of hours that people sleep each night is normally distributed. A psychiatrist or a major research center takes an SRS of 25 emotionally disturbed patients and records the average amount of sleep that each gets on a typical night. He summarizes the data and finds that Xbar=6.90 and S= 0.878. What sample size would the researcher need to use in order to decrease the margin of error of a 95% confidence interval to +-0.20 hours?
Q2 Based on your graphical and numerical analysis in Q1, which method - 1.5(IQR) or 3(SD) is more appropriate to remove outliers from the departure delay variable? Remove outliers for departure delay with the appropriate method. Store this new dataset as 'no_out_dd. You'll want to use this new dataset without outliers for use in Q3. What proportion of rows remains following the removal process multiple times. Can you please show how to do this in R Studio?
A small college is concerned that their online classes are less successful than their face-toface classes. To test this claim, the college randomly selects students from their online and face-to-face classes, gathers their average grades, and finds the summary statistics in the table below. Does the information below suggest the online classes are not performing as well as the face-to-face classes at this small college? (Assume that the assumptions and conditions for comparing two means have been satisfied, use � = 0.01) Online Grades Face to Face Grades MEAN (x) 75.2 74.8 SD (s) 3.99 4.32 COUNT (n) 27 29
A survey was conducted to study the height of people from IBRI and NIZWA. The results are shown here. The researcher is interested to examine is there a significant difference between the average height of people of the two places at a=0.05. Write the hypothesis and evaluate t-test value only. [Assuming the population variances are equal and use 2-decimal places].
A political consultant wants to sample the inhabitants of a county to estimate what proportion of all the inhabitants of the county support a certain candidate. You want to use the sampled data to construct an interval from a sample based on z-scores for the proportion, and you are considering two sample sizes: a large sample of n = 900 for more accurate results and a small sample of n = 100 to save time and money. Assuming that the sample proportion is the same in each sample, what is true about the margins of error for these two samples? The smaller sample margin of error will be approximately (select one) the larger sample margin of error. 1/9 1/3 Same as 3 times 9 times
Using a long rod that has length μ, you are going to lay out a square plot in which the length of each side is μ. Thus the area of the plot will be μ2 However, you do not know the value of μ, so you decide to make n independent measurements X1, X2,..., Xn of the length.Assume that each Xi has mean μ (unbiased measurements) and variance σ2.
