A sample (2₁,...,19) of size n = 9 has mean = 4.5 and variance 2.25. A new unit 210 = 5.5 is observed. (a) Determine the mean of the complete sample (₁,...,10). (b) Determine the variance of the complete sample (₁,....10). Hint: In solving point (b) consider the formula for calculating variances ($² E) and what you know = about its components for the smaller sample and what you would need for the complete sample.
