Please explain the step by step explanation.

Researchers wanted to know whether there was a difference in comprehension among students learning a computer program based on the text style. They randomly divided 18 students into two (2) groups of 9 each. The researchers verified that the 18 students were similar in terms of educational level, age, etc. Group 1 individuals learned the software using visual manual (multimodal instruction), while Group 2 individuals learned the software using textual manual (Unimodal instruction). The following data represent scores the students received on an exam given to them they studied from the manuals. Visual Textual 51.08 64.55 57.03 57.60 44.85 68.59 75.21 50.75 56.87 49.63 75.28 43.58 57.07 57.40 80.30 49.48 52.20 49.57 1. State the Null and Alternative Hypothesis. (2 items x 3 points) Ho: Ha: 2. Set the level of significance or alpha level to 0.05. 3. Determine the statistical test to be used. (1 item x 3 points) Dependent variable: Scores Independent variable: Style of the text (Visual and Textual) Since we are comparing the means of the scores of two independent populations/ groups, What statistical test should be used?4. Calculate the test statistic or the p-value. The results below are obtained using MS Excel. (3 items x 3 points) a. We have to determine first if the variances are equal or not equal. Formulate the null and alternative hypotheses of the statement in a.
