Question 1045053: Use technology to help you test the claim about the population mean, μ, at the given level of significance, alpha, using the given sample statistics. Assume the population is normally distributed.
Claim: μ>1210; alpha=0.09; σ=205.45. Sample statistics: x overbar=1232.09, n=250
What is the null and alternative hypotheses?
What is the standardized test statistic?
Determine the P-value?
Determine the outcome and conclusion of the test.
You can put this solution on YOUR website! Null: u = 1210
Alternative: u > 1210
Statistic = (1232.09-1210)/(205.45/sqrt(250))
