What does m represent? 4. The sample mean consumption of cheese last year
u is the population mean and m is the sample mean.
Which of the following is the appropiate rejection regions?(TS=test statistic) 5. TS>2.326
for l=.01, the rejection region for a one tailed test would be 2.326 or -2.326.
Which of the following is the value of the test statistic? 4. -0.625
z = m - u/(a/Vn) Vn = square root of n
where m = 19.5, u = 20, a = 4, n = 25
z = 19.5 - 20/ 4/V25
= -.5 / 4/5
= -.5 * 5/4
= - .625
I notice one of your problems has "m" as a population mean. Most statistics books has "m" as the sample mean. If you're instructor or book has "m" as the population mean, then m would represent "1. The population mean consumption of cheese in 1985. "
