Is there a relation between the age difference between husband/wives and the percent of a country that is literate? Researchers found the least-squares regression between age difference (husband age minus wife age), y, and literacy rate (percent of the population that is literate), x, is y=-0.0499x + 7.6. The model applied for 16 ≤x≤ 100. Complete parts (a) through (e) below. C (a) Interpret the slope. Select the correct choice below and fill in the answer box to complete your choice. For every unit increase in falls by 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. the OA. Yes-it makes sense to interpret the y-intercept because an x-value of 0 is within the realm of possibilities OB. No-it does not make sense to interpret the y-intercept because a y-value of 0 is outside the scope of the model. OC. No-it does not make sense to interpret the y-intercept because a y-value of 0 is impossible. OD. No-it does not make sense to interpret the y-intercept because an x-value of 0 is outside the scope of the model. OE. No-it does not make sense to interpret the y-intercept because an x-value of 0 is impossible. (c) Predict the age difference between husband/wife in a country where the literacy rate is 37 percent. years (Round to one decimal place as needed.) (d) Would it make sense to use this model to predict the age difference between husband/wife in a country where the literacy rate is 10% ? OA. Yes-it makes sense because an x-value of 10 is within the realm of possibilities and within the scope of the model. OB. No-it does not make sense because an x-value of 10 is outside the scope of the model. OC. No-it does not make sense because a y-value of 10 is outside the scope of the model. OD. Yes-it makes sense because a y-value of 10 is within the realm of possibilities and within the scope of the model.
