Question

Answers in blanks are not the actualy answers, just randomly chosen.

Now you decide to use a t test to test the hypothesis that there is no difference between the groups. The estimated standard error (SM1 M2) is 4.04, so the t test statistic is 2.43 Use the following tool to find the critical regions for α-.05. t Distribution Degrees of Freedom-21 .5197 4803 5000 2500 2500 0.0 0.05 0.686 3.0 2.0 1.0 1.0 2.0 3.0 0.686 The critical t-scores (the values for t-scores that separate the tails from the main body of the distribution, forming the critical regions) are Now use the tool to evaluate the null hypothesis. At a significance level of α = .05, the null hypothesis is expressive vocabulary at 18 months. . You find that you conclude that the direction the stroller faces influences a child's When you evaluated the mean difference from the independent-measures study comparing only two samples, the ANOVA and the t test resulted in conclusion

plz help

Answer 1

Solution:-

The critical scores are + 2.08

Null hypothesis is Null hypothesis: u₁ = u ₂

You find that you can conclude that the direction the stroller faces influences a child's expressive vocabulary at 18 months.

When we evaluated the mean difference from the independent t-measures study comparing only two samples, the Anova and the t test resulted in same conclusion.
