A random sample of size n1 = 25, taken from a normal population with a standard deviation σ1 = 5.2, has a sample mean = 85. A second random sample of size n2 = 36, taken from a different normal population with a standard deviation σ2 = 3.4, has a sample mean = 83. Test the claim that both means are equal at a 5% significance level. Find P-value.
