When the x² statistic calculated in a x² test is very high, it means that: the results of the test are inconclusive the difference between the observed and expected values is likely due to a factor other than chance O the difference between the observed and expected values is likely due to chance alone there is no difference between the observed and expected values the experiment was set up incorrectly and should be repeated

25) A data set has a mean equals (7), if we multiply all values of the data set by (3), then the mean will become (21). Select one: True False
1. One-way analysis of variance is used to test equality of means among more than two populations. The F- statistic is used to conduct the test. It is argued that the more divergent are the means the higher the F-statistic will be. Explain the logic behind this argument.
When dealing with a set of numbers such as these attached, do you always group together for a raw score + z score to then answer for probability?The main question is: what is the corresponding x score for each raw score?From there, I need to determine the probability of a raw score greater than 4; less than 2; between 4 & 6; between 3 & 6 but my text only talks about grouping together (like for how I would calculate the mean and SD).Do I base my probability off the set or is there a more specific way to go about it?
9. In a telephone survey of 800 registered voters, the data are cross classified both by gender of respondent and by respondent's opinion on an environmental bond issue. Men Women Bond issue For 450 160 Against 150 40 We want to know whether there is good evidence that one's gender influences whether a person is for or against the bond issue. Use the chi-square test to answer this question. State the hypotheses, discuss conditions, perform calculations, and report your conclusions.
2- In statistics we may compute a result that is statistically significant but not meaningful- give an example of this.
unrest and violence on one southern campus had decreased by 62% from 10 years ago. four out of then americans brush their teeth daily. which of the following is true regarding these two statements? a. these statements are derived from inductive statistics b. all of the given statements are sample parameters rather than population statistics. c. statistics, from one of it definitions, constitutes a collection of such statements. d. these types of statements are usually found to be exampls of lying with statistics. e. nonof these is correct.
Suppose scores on a mathematics test have a mean 60 and standard deviation 20 while scores on an English test have a mean 60 and standard deviation 10. Bob gets 80 on both tests. a) On which test did Bob do better relative to his classmates? Explain. b) The scores on the tests each approximately follow a normal distribution and there are 50 students in each class How many students did better than Bob in each case? Page 8 of 11

6. In March 2010, the Pew Research Group surveyed 1708 adults Americans and asked, "Do you believe the USA was right or wrong to in using military force against Iraq?" Of the 1708 adults surveyed, 1186 stated the USA made the correct decision. In January of 2020, the Pew Research group asked the same question to 1375 adult Americans and found that 934 still share the same opinion that military force was correct. Is there significant evidence to support the claim that this proportion is lower now than it was in 2010? Use alpha = 0.05 a. Set up the Hypotheses and indicate the claim H0: Ha: b.
