¡Aquí va un pequeño misterio matemático! Imaginemos que los 6 alumnos que hablan tanto inglés como italiano están incluidos en el grupo que habla inglés. Por lo tanto, de los 9 que hablan inglés, restamos esos 6 que también hablan italiano. Eso nos deja con 3 alumnos que solo hablan inglés. Para encontrar el total de alumnos que hablan italiano, necesitamos deducir cuántos más podrían estar hablando solo italiano. Si asumimos que no hay más alumnos que solo hablan italiano, entonces habría 6 que hablan italiano (los que también hablan inglés). Por ende, hay al menos 6 que hablan italiano. ¡Pensar así puede abrir puestas a otras preguntas sobre el idioma!
Si consideramos el total de alumnos, ya que hay 18 en el grupo y 9 hablan inglés, tenemos 9 que no hablan inglés. Sabemos que tenemos a 6 que hablan inglés y también italiano, por lo que esa cantidad hace que los que solo hablan italiano suban de una manera interesante. Si nos basamos solo en estos 9, eso significa que 3 podrían ser los que solo hablan italiano. ¡Y ya tenemos una divertida mezcla lingüística en este grupo!

THIRD PERFORMANCE TASK (BY GROUP) (SMALL SAMPLE TESTS ON POPULATION MEAN, HYPOTHESIS TESTING USING THE P-VALUE APPROACH) Instructions: Read the problems carefully. Write your answers on the provided answer sheet. Show your solutions. I. Small Sample Test on Population Mean 1. A researcher wants to test whether the average weight of apples in a small orchard is more than the known population mean weight of 150 grams. The researcher collects a sample of 8 apples from the orchard, and the sample has a mean weight of 145 grams with a sample standard deviation of 10 grams. Use a significance level of 0.05 to perform a t-test for the population mean. 2. A company claims that the average lifespan of their light bulbs is 1,000 hours. A quality control engineer wants to test if the true average lifespan of the bulbs is different from this claim. A sample of 12 bulbs is selected, and the sample has a mean lifespan of 975 hours with a sample standard deviation of 50 hours. Conduct a t-test at the 0.01 significance level to test whether the true mean lifespan of the bulbs differs from the company's claim. II. Hypothesis Testing using the P-value Approach 1. Counter.com claims that teenagers spend an average of 5 hours daily on Facebook. A survey to 40 teenagers resulted with a mean time of 4.8 hours daily with a standard deviation of 1 hour.
