Answer #1

>> 3 groups were compared

>> 39 research participants

>> result is statistically significant

Explanation:

> Treatment degrees of freedom = 2

So, the number of groups = 2 + 1 = 3

> Error degrees of freedom = 36

Total degrees of freedom = 2 + 36 = 38

So, total number of participants = 38 + 1 = 39

> Since, the p-value is less than the significance level of 0.01, we reject the null hypothesis and conclude that the result is statistically significant.

Statistical significance (alpha level; p-value) reflects the odds that a particular finding could have occurred by chance. If the p-value for a difference between two groups is 0.05, it would be expected to occur by chance just 5 times out of 100 (thus, it is likely to be a “real” difference). We define a p-value of less than 0.05 to indicate statistical significance. Suppose a pizza place claims their delivery times are 30 minutes or less on average but you...

Suppose that the overall F-test obtained from performing a one-way ANOVA resulted in a p-value that was not statistically significant. Which of the following CANNOT be true? The variability within the groups is very large compared to between-group variability. The variability between the groups is very large compared to within-group variability. The ratio of the between and within variability was not sufficiently large. The F-statistic was not larger than the critical value obtained from the F-distribution.

A child dying from an accidental poisoning is a terrible incident. Is it more likely that a male child will get into poison than a female child? To find this out, data was collected that showed that out of 1830 children between the ages one and four who pass away from poisoning, 1031 were males and 799 were females (Flanagan, Rooney & Griffiths, 2005). Do the data show that there are more male children dying of poisoning than female children?...

Question: In 2008, there were 507 children in Arizona out of 32,601 who were diagnosed with Autism Spectrum Disorder (ASD) ("Autism and developmental," 2008). Nationally 1 in 88 children are diagnosed with ASD ("CDC features -," 2013). Is there sufficient data to show that the incident of ASD is more in Arizona than nationally? Test at the 2% level.

Are there more children diagnosed with Autism Spectrum Disorder (ASD) in states that have larger urban areas over states that are mostly rural? In the state of Pennsylvania, a fairly urban state, there are 245 eight year olds diagnosed with ASD out of 18,440 eight year olds evaluated. In the state of Utah, a fairly rural state, there are 45 eight year olds diagnosed with ASD out of 2,123 eight year olds evaluated ("Autism and developmental," 2008). Is there enough...

question 1 1) Consider a significance test for a null hypothesis versus a two-sided alternative. State all values of a standard normal test statistic z that will give a result significant at the 10% level but not at the 5% level of significance. (Sec. 6.2) You perform 1,000 significance tests using α = 0.01. Assuming that all the null hypotheses are true, how many of the test results would you expect to be statistically significant? Explain your answer. (Sec. 6.3)...

exercise and the tukey hsd test: in how it works 11.1, we conducted a one-way between-groups anova on an abbreviated data set from research by irwin and colleagues (2004) on adherence to an exercise regimen. Participants were asked to attend a monthly group education program to help them change their exercise behavior. Attendance was taken and participants were divided into three categories: those who attended fewer than 5 sessions, those who attended between 5 and 8 sessions, and those who...

T F 1. A p-value of .008 in hypothesis testing means there is only a .8% chance we could get such sample statistics from the population if the null hypothesis is as stated. Such an event is considered unlikely and we would reject the null hypothesis. T F 2. As a general rule in hypothesis testing, it is always safer to set up your alternate hypothesis with a greater-than or less-than orientation. _____3. If the level of significance is .02...

A) A child psychologist conducts a study to test whether infants born prematurely begin to walk earlier than do infants in general. If the research hypothesis is actually true – infants born prematurely do begin to walk earlier than infants in general – and the psychologist has a 25% chance of making a Type II error, what is the power of the study? (give your answer as a proportion - between 0 and 1) B) If there really is NOT...
