The weight (kg) of chocolate is normally distributed with population mean ? and population standard deviation 1.2 kg. The manager claimed that the weight of this chocolate is 9.0 kg. We are now doing a hypothesis testing: ?0: ? = 10.1 ?? ?1: ? > 10.1 at 5% significance level and the sample mean is 11.4 kg. (a) (10) Find the least sample size such that the null hypothesis will be rejected. (b) (5) Find the rejection region in term...

Suppose that you know that the weight of standard poodles is Normally distributed with a standard...

Suppose that you know that the weight of standard poodles is Normally distributed with a standard deviation of 4 pounds. You take an SRS of 10 poodles and find their average weight to be 52 pounds. Perform a significance test with this data to see if the average weight of standard poodles is 49 pounds or if it is actually larger than that. Use a 3% significance level. Fill in the blanks with each requested value. Write all numbers as...
