You know that X is a binomial distribution. and that its expected value is G and its standard error is 2. What is the probability that X outputs 1? Explain why \"All Gaussian distributions with mean 45\" is a statistical model. What is a parameter for this statistical model?

Solution

X is binomial with mean =6 std error =2

np = 6 and npq = 4

Hence q = 2/3 and p = 1/3

P(x=1) = 1/3

-----------------------------------------

Mean =45 means

estimate for population mean = 45

Hence parameter for statistical model is the population mean = 45
