1. If F = 2.90, you have five conditions and 85 participants, what would you conclude about your study?

A) Your F value is statistically significant

B) Your F Value is not statistically significant

C) F obtained value does not exceed either the critical value at the p < .05 level or the p< .01 level

D) There is not enough information to answer this question

Given F value is 2.90,

There are five conditions, therefore degrees of freedom for treatments are dftreat=4

There are total 85 participants, therefore total degrees of freedom are dftotal=84

Hence error degrees of freedom is

dferror=dftotal-dftreat

dferror=84-4=80

Therefore test statistic follows F distribution with (4, 80) degrees of freedom.

Critical F value is obtained by using f table,

Since F value exceeds critical value.

A) F value is statistically significant.
