### Answers:
a-1] ANOVA table is attached above.
a-2] the critical value of F = 9.33
b] t=sqrt(F) = 1.015
c] since test statistics F is less than 9.33 we fail to reject H0.
Fail to reject H0. there is not statistically significant difference in the mean scores.

Does delaying oral practice hinder learning a foreign language? Researchers randomly assigned 26 beginning students of Russian to begin speaking practice immediately and another 26 to delay speaking for 4 weeks. At the end of the semester both groups took a standard test of comprehension of spoken Russian. Suppose that in the population of all beginning students, the test scores for early speaking vary according to the N(34, 8) distribution and scores for delayed speaking have the N(32, 6) distribution....
