Spinocerebellar ataxia type 1 is a neurodegenerative disease marked by the gradual loss of motor skills and culminating with death. It is ca ued by an expanded CAG repeat in the coding region of the Ataxin-1 gene. Fryer et al. {2011) investigated the possible benecial eects of exercise in treating the disease. They used a mild exercise regimen in a mouse model of the disease. The life spans (in days} are given below for six exercised mice and six mice not given the exercise regimen. The data and 95% condence intervals are shown in the graph below. Based on this graph, is it possible to unambiguously predict the outcome of a formal test of the null hypothesis that the means of the two groups are the same? Answer TRUE for 'yes' and FALSE for 'no
