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 a9e), y, and Iteracy rate (percent of the population that is iterato). X, is y=-004122+6.7. The model applied for 23sxs 100. Complete parts (a) through (e) below
(a) interpret the slope Select the correct chole below and fill in the answer box to complete your choice
For every unit increase in
tals by Bluntson average
(Type an integer or decimal. Do not found)
(b) Does it make sense to interpret the intercept? Explain. Choose the correct answer below
A Yes makes sense to interpret the intercept because an x-value of 0 is within the realm of possibilities
OB Not does not make sense to interpret the Intercept because an x-value of O is outside the scope of the model
OC. Not does not make sense to interpret the intercept because a y value of 0 is impossible
OD. No do not make sense to interpret the intercept became an x-value of Ois impossible
O No does not make sense to interpret the entercept 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
yearsRound to one decimal place as needed)
