What is type 1 error in ANOVA Choose all that apply.
Error that leads to false negatives.
Error that leads to false positives.
Error that indicates the data is not significant when it is.
Error that indicates data is significant when it is not.
Solution:
We have to choose correct statements from the given statements.
What is type 1 error in ANOVA
Answer :
Error that leads to false positives.
Error that indicates data is significant when it is not.
Explanation:
type 1 error is when "we reject the null hypothesis , but the null hypothesis is true.
Type 2 error is when " we fail to reject the null hypothesis , but the null hypothesis is Not true.
So ,
type 1 error is Error that indicates data is significant when it is not.
and Error that leads to false positives.

The information for a particular area and radon testing is as follows: • 4 of 100 homes have radon gas problems • A test for radon gas is 85% accurate • The test is performed in 10,000 homes in this area a. Using the table below, create a matrix similar to the one in the Type I-Type II error notes. 1. Label the cells as true positives, false positives, false negatives, true negatives and Type I and Type II errors....

After observing statistically significant ANOVA results, Bonferroni-corrected inferences to determine which groups differ from each other require the following steps (select all that apply): o Select one or more: a. Compute the type I error rate allowable for each pairwise comparison in order to insure that the type I error rate across all comparisons does not exceed some pre-specified level b. Determine that the difference between a specific pair of groups is statistically significant if the t-test p-value is less...

Type I error is: A. Deciding the null hypothesis is true when it is false B. Deciding the alternative hypothesis is true when it is true C. Deciding the null hypothesis is false when it is true D. Deciding the alternative hypothesis is true when it is false E. All of the above F. None of the above Type Il error is: A. Deciding the alternative hypothesis is true when it is true B. Deciding the alternative hypothesis is false...
When a false null hypothesis is not rejected, a.we commit a type i error b. we choose the wrong alpha c. we commit a type ii error d. we commit a type ii error e.we rely on the p value to see the probability of the null hypothesis being correct
Question 1 For ANOVA: the null hypothesis is: Mu1 = Mu2 = Mu3......etc True False Question 2 For ANOVA: the alternative hypothesis is: Mu1 ≠Mu2 ≠Mu3......etc. True False Question 3 Both ANOVA and Chi square tests are always right tail tests True False Question 4 For ANOVA, you only complete a Tukey's means comparisons test if the overall F* value was significant (i.e., p<0.05) True False Question 5 Both F and Chi Square distributions vary with df True False Question...
