A certain medication is supposed to contain 350 mg of the active ingredient per pill. It is known from previous work that this content is normally distributed with a standard deviation of 3.5 mg. Suppose a random sample of 5 pills are taken, and the average content is 346.4 mg.

a) What would our conclusion be if we test H0 : u = 344 , H1 : u not equal to 344 at the level a = 0.05 ?

b) What would our conclusion be if we test H0 : u = 342, H1 : u not equal to 342 at the level a = 0.05 ?

A certain medication is supposed to contain 350 mg of the active ingredient per pill. It is known from previous work that this content is normally distributed with a standard deviation of 3.5 mg. Suppose a random sample of 5 pills are taken, and the average content is 346.4 mg. Is the mean pill content not 350 mg? a) For this example, if we were to test our hypothesis at the level a= 0.01 what would our conclusion be ?...

A certain cold medication must contain the amount of the active ingredient as 25 mg per dose to be effective. If the medication contains more than 25 mg per dose, it’s dangerous to health. If it is less than 25 mg per dose, the medication is not effective. A random sample of 75 doses was taken to a lab and analyzed to determine the actual amounts of the active ingredient in each of these 75 doses. They found 24.82 mg...

We have these hypotheses: H0: the amount of active ingredient in a pharmaceutical pill is 5 mg H1: the amount is below 5 mg We can take a random sample of 40 such pills and find the amount of active ingredient in them, and let the sample average be x-bar. We also know that the standard deviation of the amount of active ingredient is 0.3 mg. If H0 is right, what is the (approximate) distribution of ( x-bar minus 5)...
