I am really confused on how to interpret the slope and y-intercept related to least square regression. Can anyone explain how can we interpret these types of question. The question is given below: - Math54 Sec#3473 Madison Williams 12/13/22 4:48 PM Homework: Chapter4.1-4.3 Homework Question 14, 4.2.15 HW Score: 83.31%, 24 99 of 30 points Part 5 of 5 Points: 0.14 of 1 Save Question list K 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 = -0.0585x + 6.8. The model applied for 19 sx 100 Complete parts (a) through (e) below. Question 10 (a) Interpret the slope. Select the correct choice below and fill in the answer box to complete your choice. Question 11 For every unit increase in literacy rate, the age difference falls by 0.0585 units, on average. (Type an integer or decimal, Do not round.) Question 12 (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. % Question 13 B. No-it does not make sense to interpret the y-intercept because an x-value of 0 is impossible. 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 D. No-it does not make sense to interpret the y-Intercept because a y-value of 0 is outside the scope of the model. Question 14 XE. 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 34 percent % *Question 15 4.B 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%? Question 16 X A. No-It does not make sense because a y-value of 10 is outside the scope of the model B. Yes-it makes sense because an x-value of 10 is within the realm of possibilities and within the scope of the model. Question 17 )C. Yes-it makes sense because a v-value of 10 is within the realm of possibilities and within the scope of the model. Help me solve this View an example Get more help Similar question Reply
