t test for 2 groups and for ANOVA it is for more comparing than 2 groups
t and ANOVA test used to test for significant difference in means
\(\displaystyle{H}_{{o}}:\mu_{{1}}-\mu_{{2}}\)
\(\displaystyle{H}:\mu_{{1}}=\mu_{{2}}=\mu_{{3}}\) in ANOVA
Assumes popualtion variances to be equal samples are drawn from popualtions fand sample should follow normal distribution
ANSWERS:
They assume normality within groups
They assume homogenity of variances
They make inferences about population means .

Give a ffull answer its true or false: When an ANOVA comparing the means of 3 groups indicates that at least one group is different from the others, a common follow-up analysis to determine which group(s) is (are) different is pairwise two-sample t-tests each assessed using i) the pooled standard deviation when calculating the standard error for the difference in means and ii) a Bonferonni-corrected alpha level of 0.0167 to control the type I error rate for the overall inference to 5%

If John, Trey, and Miles want to know how’ | many two-letter secret codes there are that don't have a repeated letter. For example, they want to : count BA and AB, but they don't want to count“ doubles such as ZZ or XX. Jobn says there are 26 + 25 because you don’t want to use the same letter twice; that’s why the second number is 25.
‘Trey says he thinks it should be times, not plus: 26-25, Miles says the number is 26-26 ~ 26 because you need to take away the double letters. Discuss the boys’ ideas, Which answers are correct, which are not, and why? Explain your answers clearly and thoroughly, drawing ‘on this section’s definition of multiptication.. -
