Exercise 1: In a management trainee program‚ 80% of the trainees are female‚ 10% male. A total of 70% of the females attended college‚ while 60% of the males attended college. A management trainee is selected at random. 1. What is the probability that the person selected is a female who did NOT attend college? = 0.80 * 0.30 = 0.24 (24%) 2. What is the probability that the person selected is a female who did attend college? = 0.80 * 0.70 = 0.56 (56%) 3. What is the probability that the person

SECTION A (You should attempt all 10 questions) A1. The sample mean is an unbiased estimator for the population mean. This means: (A) The sample mean always equals the population mean. (B) The average sample mean‚ over all possible samples‚ equals the population mean. (C) The sample mean is always very close to the population mean. (D) The sample mean will only vary a little from the population mean. A2. The central limit theorem tells us that the sampling distribution of the mean is approximately

Smoking is a major modifiable risk factor for diseases and premature death‚ and can be prevented with health promotion and disease prevention strategies. This paper will focus on the clinical issue regarding tobacco use among the female adolescent population. Since female adolescents are at the beginning stage of their reproductive years‚ introduction of smoking cessation early will help alleviate foreseeable health problems. The purpose of this paper is to examine how the application of the Transtheoretical

DETERMINATION OF VITAMIN C CONTENT IN COMMERCIAL (CENOVIS) TABLET ABSTRACT In this experiment‚ the vitamin C content of a commercial tablet is determined and compared with the manufacturers’ specification. Vitamin C is water-soluble and is an enantiomer of ascorbic acid. (Commercial vitamin C is often a mixture of ascorbic acid and other ascorbates.) Ascorbic acid‚ C6H8O6‚ is a reducing agent that reacts rapidly with iodine (I2). As the iodine is added during the titration‚ the ascorbic acid is

Title: Determination of Iron in Natural water by Spectrophotometry. Aim: To determine the iron in natural water by spectrophotometry. Abstract: The iron in natural water was determined by utilizing spectrophotometric analysis. That was done by measuring the absorbance of five Fe(oPH)2+3 standards at 510 nm. From that information‚ a calibration curve was plotted and used to find the amount of Fe2+ that was in two unknown water samples based on the absorbance readings obtained with them at 510nm. The
