OneWorld Inc. makes software for learning languages that is targeted to business executives. The company wants to determine whether there is evidence that the two approaches it uses to teaching languages to native English speakers (Method A and Method B) differ in effectiveness in terms of the mean number of recalled vocabulary words in that language after a month of learning. The company will evaluate the two methods using seven different languages, since languages differ in difficulty in general regardless of how they are taught Seven executives (one per language) are recruited to use the software to learn vocabulary using Method A, and another seven individuals are recruited to learn vocabulary using Method B. After a month, each executive completed a test of word recall. Using your answers to the previous questions, state the rejection region and the conclusion, using an a = 0.05 level of significance, by filling in the appropriate blanks in the statement below. For blanks that appear before words or phrases in parentheses that are separated by a "/", type one of the words or phrases in the parentheses for that blank. The rejection region is all t . Based on the value of the test statistic calculated above, the company will (reject/fail to reject) the null hypothesis. The company (can/cannot) conclude that Method A differs from Method B in the mean number of recalled words
