Is there a relation between the age difference between husbandfwives 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 [peroe nt of the population that is literate}. x, is ;= - 0.045% + 18. The model applied for 21 s x s 100. Complete parts (a) through {e} below. E (a) Interpret the slope. Select the correct choice below and ll in the answer box to complete your choice. For every unit Increase in literacy rate. the falls by 0.0459 units. on average. (Type an integer or decimal. Do not round.) (bi Does it make sense to interpret the y-intercept? Explain. Choose the correct answer below. 0 A. Yesit makes sense to interpret the y-intercept because an x-valus of 0 is within the realm of possibilities. O B. Noit does not make sense to Interpret the y-lntercept because an inc-value of c is impossible. (i) C. Noit does not make sense to interpret the y-intercept because a y-value of 0 Is outside the scope of the model. 0 D. Noit does not make sense to interpret the y-intercept because an x-value of 0 is outside the scope of the model. 0 E. Noit does not make sense to interpret the y-intercept because a y-value of O is impossible. to) Predict the age difference between husbandhv'rfe in a country where the literacy rate is 36 percent. |:| years {Round to one decimal pl ace as needed.) '1'.\" Would it make sense to use this model to predict the age ditlerence between husbandiwite in a country where the literacy rate is 15%? O A. Yesit makes sense because an x-value of 16 is within the realm of possibilities and within the scope ot the model. 0 B. Yesit makes sense because a y-value of 16 is within the realm of possibilities and within the scope or the model. (E) c. Nolt does not make sense because an x-velue of 1a is outside the scope of the model. 0 D. Noit does not make sense because a y-value of 16 Is outside the scope of the model. to) The literacy rate in a country is 99% and the age difference between husbands and wives is 2 years.
