Solution

Two assumptions of the usual normal linear model used for the reported coefficient Student t-tests are:

The errors are independent random variables across mice.
Conditional on the predictors, each error has a normal distribution with mean zero and the same variance $σ^{2}$ : $ε_{i} ∣ w_{i}, s_{i} \sim N (0, σ^{2})$ .

The second statement includes homoscedasticity. Normality concerns the conditional errors, rather than requiring the weights themselves to have a normal distribution.
