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 0545x + 7 4 The model applied for 22 5xs 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 the 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. 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 impossible O C. 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 D. No-it does not make sense to interpret the y-intercept because an x-value of 0 is impossible O E. 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) Predict the age difference between husband/wife in a country where the literacy rate is 31 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 16%? O A. No-it does not make sense because an x-value of 16 is outside the scope of the model O B. Yes-it makes sense because an x-value of 16 is within the realm of possibilities and within the scope of the model. O C. Yes-it makes sense because a y-value of 16 is within the realm of possibilities and within the scope of the model 22 O D. No-it does not make sense because a y-value of 16 is outside the scope of the model. om (e) The literacy rate in a country is 98% and the age difference between husbands and wives is 2 years. Is this age difference above or below the average age 122 difference among all countries whose literacy rate is 98%? Select the correct choice below and fill in the answer box to complete your choice. pm (Round to one decimal place as needed.) O A. Above-the average age difference among all countries whose literacy rate is 98% is years 9/22 pm O B. Below-the average age difference among all countries whose literacy rate is 98% is years course (MATH1
