A study was carried by a researcher found that individuals who practice the yoga with a combination of specific breathing techniques and meditation principles lower their blood pressure significantly. A sample of 225 male yoga practitioners was randomly selected. They practice yoga for an average of 8.5 hours per week with a standard deviation of 2.25 hours. Does this suggest that, on average, men who use yoga meditate more than 8 hours per week? Test this using a significance level of 5%.
