Problem #1( An Electronics firm employs 15 people whose yearly salaries (in hundred thousand of pesos) are as follows: 25.0 25.7 25.7 26.6 27.2 27.3 27.3 27.3 27.3 27.8 27.8 28.4 28.4 29.0 29.0 a) Let X be the yearly salary for any employee. Find the probability distribution of X. b) Find the Mean, Variance, and Standard Deviation of the probability distribution (Round your answer in nearest hundredths). c) Construct the probability histogram for the random variable X. Problem #2 Five hundred children participaued in a field demonstration. Their heights average 110 cm with a standard deviation of 6 cm. a) Sketch the normal curve of the given situation. b) What is the probability that a child picked at random has a height greater than 116 cm? c) What is the probability that the height of a child picked at random is less than 104 cm? d) What is the probability that the height of a child picked at random is between 110 cm and 122 cm? e) How many children have heights between 98 cm and 104 cm? ) How many children belong to the upper 15% of the group?
