A pharmaceutical manufacturer is concerned that the impurity concentration in pills should be less than or equal to 3% on average. It is known that, from a particular production process, impurity concentrations follow a normal distribution with standard deviation of 0.4%. A random sample from a production process was checked, and the sample mean impurity concentration was found to be 3.07%. A) Test the concern of manufacturer at 5% level with test statistics as well as B) find probability value and interpret please. C) Interpret the results for managers

QUESTION 9 As part of quality control, a pharmaceutical company tests a sample of manufacturer pills to see the amount of active drug they contain is consistent with the labelled amount. That is, they are interested in testing the following hypotheses: H0:μ=100H0:μ=100 mg (the mean levels are as labelled) H1:μ≠100H1:μ≠100 mg (the mean levels are not as labelled) Assume that the population standard deviation of drug levels is 55 mg. For testing, they take a sample of 1010 pills randomly...

A horseshoe for horseshoe pitching should not weigh less than 2.625 pounds. In a sample of 28 horseshoes. the average weight is 2.48 pounds with a sample standard deviation of 0.3 pounds. We wish to test H0: mu equals 2.625 against HA: mu space less than space 2.625 at alpha space equals space 0.05. You may assume the distribution of weights is approximately normal. a) Are the hypotheses being tested right-tailed, left-tailed, or two-tailed? b) Determine the value of the...

The analytical concentration of lactic acid in blood is generally less than 1.20 x 10-4 M, corresponding to the sum of [lactate] and [lactic acid]. During strenuous exercise, however, oxygen in the muscle tissue is depleted, and overproduction of lactic acid occurs. This leads to a condition known as lactic acidosis, which is characterized by elevated blood lactic acid levels (approximately 5.00 x 10-3 M). The pKa of lactic acid is 3.9. 1. What is the actual lactic acid concentration...

A computer manufacturer estimates that its cheapest screens will last less than 2.8 years. A random sample of 61 of these screens has a mean life of 2.4 years. The population is normally distributed with a population standard deviation of 0.88 years. At α=0.02, what type of test is this and can you reject the organization’s claim using the test statistic?
