They wanted to check whether data would support this hypothesis. The following is the output for the t-test: T-value: -2.10 P-Value: .02 Using a significance level of .05, what conclusion would you make The data do not provide sufficient evidence that the mean fluency score for Spanish speakers is larger than that of Portuguese speakers. The data do provide sufficient evidence that the mean fluency score for Spanish speakers is larger than that of Portuguese speakers. The data do provide sufficient evidence that the mean fluency score for Spanish speakers is not different than that of Portuguese speakers. The data do not provide sufficient evidence that the mean fluency score for Spanish speakers is not d
