The sulfate ion concentration in natural water can be determined by measuring the turbidity that results when an excess of BaCl2 is added to a measured quantity of the sample. A turbiditimeter, the instrument used for this analysis, was calibrated with a series of standard Na2SO4 solutions. The following data were obtained for the calibration:

A certain dosage of radiation, measured in kilorads, must be given to the tumor near the brain. The dose delivered must be sufficient to kill the malignant cells but the aggregate dose must not exceed established tolerance levels for the brain. Two beams which would deliver radiation exposure to the cells will be used. The goal is to select certain beam durations that would generate the best dosage distribution by minimizing the radiation absorbed by the brain. The data for the radiation therapy is given below: a. Define the variable used: b. LP Model: c. Identify the feasible region d. Corner Points and the objective functions: e. Optimal Solution (final answer):
Please review Section 11.1. Are you an impulse shopper? A survey of 500 grocery shoppers indicated that 16% of males and 42% of females make an impulse purchase every time they shop. Assume that the survey consisted of 250 males and 250 females. Let group 1 be the males and let group 2 be the females.alpha = 0.05H0: pie = pieH1: pie not = pie Calculate the test statistic: (Round to three decimal places as needed.)Determine the critical value: (Round to three decimal places as needed.)State the Conclusion:
A fast food restaurant estimates that the mean sodium content in one of its breakfast sandwiches is no more than 924 milligrams. A random sample of 58 breakfast sandwiches has a mean sodium content of 918 milligrams. Assume the population standard deviation is 24 milligrams. At α=0.10, do you have enough evidence to reject the restaurant's claim? Complete parts (a) through (e). Also find the critical values.
