Final answer:
To calculate the number of standard deviations away from the mean a bag of potato chips weighing 15.9 ounces is, we can use the formula z = (x - μ) / σ. Plugging in the values, we have z = (15.9 - 14.5) / 0.7 = 2.
Step-by-step explanation:
To calculate the number of standard deviations away from the mean a bag of potato chips weighing 15.9 ounces is, we can use the formula z = (x - μ) / σ, where x is the given weight, μ is the mean, and σ is the standard deviation.
Plugging in the values, we have z = (15.9 - 14.5) / 0.7 = 2, which means the bag of potato chips is 2 standard deviations away from the mean.
