If a random sample of 225 men who practice TM meditate 8.5 hours a week. The population standard deviation is known to be 2.25 hours, does this suggest that, on average, men who use TM meditate more than 8 hours per week? Use a significance level of 0.01. The critical value is:

a) 2.604

b) 2.326

c) 2.347

d) 2.054

Answer 1

The critical value the Solution Given that Mean (a) = 8.5 standard deviation (T) = 2.25 Samples (n) = 225 significance level 6)=0.01 (... From Critical value calculator -> Option 'B' is correct.
