"Researchers studied the length of time spent on individual home visits by
public health nurses.They wished to answer the following question: does the
mean length of home visit differ among different age groups of nurses?"
1. What is the response variable of interest, and what data type is it?(
qualitattive or quantitative)
2. Can we analyze the researchers' data by fitting a OLS simple linear
regression model? If not , how can you analyze the data?

y_ij is the j-th mean length of home visit corresponding to the i-th age
group. The model is
y_ij = \eta + \tau_i + e_ij,i=1,2,..., j= 1,...,n_i
y_ij is quantitative, \tau_i is qualitative |
