(a) Why is an unbiased statistic generally preferred over a biased statistic for estimating a population characteristic? An unbiased statistic is generally preferred over a biased one because the unbiased statistic --Select-- , on average, give the correct value for the population characteristic being estimated, while the biased one -Select--v (b) Does unbiasedness alone guarantee that the estimate will be close to the true value? Explain. Unbiasedness alone --Select- v guarantee that the value of the statistic will be close to the true value of the population characteristic, since, if the statistic has a large standard deviation, values of the statistic will tend to be --Select--- v the population characteristic. (c) Under what circumstances might you choose a biased statistic over an unbiased statistic if two statistics are available for estimating a population characteristic? A biased statistic might be chosen in preference to an unbiased one if the biased statistic has a Select- v standard deviation than that of the unbiased statistic, and as a result values of the biased statistic are more likely to be --Select v the population characteristic than values of the unbiased statistic.

True or False: Important differences are always statistically significant if a large sample size is used.
Researchers were interested in assessing whether stress levels are different at the beginning of the semester compared to finals week. To test this, stress was measured in 5 students at the start of the semester and then again at the end of the semester during finals week. Participant Stress 1 Stress 2 Difference Score (Di) (Di - Mdiff)2 1 22 22 0 2 32 34 -2 3 24 25 -1 4 28 30 -2 5 26 29 -3 What is the observed test statistic (i.e., tobs)? Round to 2 decimal places.
What is the null hypothesis? Why do we want to reject our null hypothesis? The first step is the find the mean of our sample and compare it to the "hypothesized" mean of our null hypothesis—why do we do that? We use the results of our first step to calculate a test-statistic. Why is this important and how does it relate to the concept of z-score, which we learned a few weeks ago? What is a p-value? What role does it play in the rejection of the null hypothesis? What does it mean to reject the null hypothesis? Does that guarantee that the null hypothesis is false?
An ANOVA test is a way to find out if survey or experiment results are significant. In other words, they help you to figure out if you need to reject the null hypothesis or accept the alternate hypothesis. ANOVA is a test between groups to see if there’s a difference between them. State the four assumptions required for one-way ANOVA. How crucial are these assumptions? One-way ANOVA is a procedure for comparing the means of several populations. It is the generalization of what procedure for comparing the means of two populations? In one-way ANOVA, identify the statistic used a. as a measure of variation among the sample means. b. as a measure of variation within the samples. c. to compare the variation among the sample means to the variation within the samples. 4. What is a two-way ANOVA?
True or false: The point estimate for the population mean of an xdistribution is computed from a random sample of the xdistribution.
True or False: In order to perform an analysis of variance (ANOVA), the response variable must be quantitative.
-what kinds of questions can we test with a t test? -How do you know if two samples are statistically different from each other? In other words, what statistics will tell you if your results are statistically significant?
Which best illustrates the distinction between statistical significance and practical importance? Multiple Choice "This year, 360 of 440 statistics students at Oxnard Technical College rented their textbooks, compared with 110 of 330 students last year. This is a significant increase." "Our new manufacturing technique has increased the life of the 80 GB USB AsimoDrive external hard disk significantly, from 240,000 hours to 250,000 hours." "In 50,000 births, the new vaccine reduced the incidence of infant mortality in Morrovia significantly from 14.2 deaths per 1000 births to 10.3 deaths per 1000 births." "The new Sky Penetrator IV business jet’s cruising range has increased significantly from 3,975 miles to 4,000 miles."
