The probability that a slice contains less than 154 milligrams of sodium given that a randomly chosen slice of white bread has a mean of 110 milligrams with a standard deviation of 25 milligrams can be calculated using z-score.What is the probability that a slice contains less than 154 milligram of sodium?The formula for calculating z-score is given below;z= (x-μ) / σwhere;x is the value of interestμ is the mean of the populationσ is the standard deviationIn this case;x = 154μ = 110σ = 25To compute the z-score;z= (154-110) / 25z= 1.76To find the probability that the value is less than 154 milligrams, we look up the value of 1.76 on the z-table.Using a z-table or calculator, the probability that a slice contains less than 154 milligrams of sodium is about 0.960.
