Next question Is there a relation between the age difference between husband/wives and the percent of a country that is literate? Researchers uares regression between literacy rate (percent of the population that is literate), x, is y = - 0.0487x + 7.4. The model applied for 18 5 x$ 100. Complete parts (a) through (e) below. (a) Interpret the slope. Select the correct choice below and fill in the answer box to complete your choice. For every unit increase in literacy rate, the age difference falls by 0.0487 units, on average. (Type an integer or decimal. Do not round.) (b) Does it make sense to interpret the y-intercept? Explain. Choose the correct answer below. O A. Yes-it makes sense to interpret the y-intercept because an x-value of 0 is within the realm of possibilities. O B. No-it does not make sense to interpret the y-intercept because a y-value of 0 is outside the scope of the model. C. No-it does not make sense to interpret the y-intercept because an x-value of 0 is impossible. &D. No-it does not make sense to interpret the y-intercept because an x-value of 0 is outside the scope of the model. O E. No-it does not make sense to interpret the y-intercept because a y-value of 0 is impossible. (c) Predict the age difference between husband/wife in a country where the literacy rate is 26 percent. years (Round to one decimal place as needed.)
