What's inside
- Weights of machine-filled flour bags follow N(mu = 1003, sigma = 7) in g. Find P(994.6 < X < 1000.9). Use the standard normal CDF Phi and round to 4 decimal places.
- Scores on a standardised exam follow N(mu = 544, sigma = 56) in points. Find the probability that a randomly chosen value is greater than 555.2 points. Use the standard normal CDF Phi and round to 4 decimal places.
- Adult heights in a population follow N(mu = 167, sigma = 8) in cm. Find the probability that a randomly chosen value is greater than 151.8 cm. Use the standard normal CDF Phi and round to 4 decimal places.
- Systolic blood pressure of adults follow N(mu = 116, sigma = 11) in mmHg. Find P(97.3 < X < 110.5). Use the standard normal CDF Phi and round to 4 decimal places.
- Weights of machine-filled flour bags are normally distributed with mean 1009 g and standard deviation 7 g. Find the z-score of a value of 1020.2 g, rounded to 2 decimal places.
- Scores on a standardised exam follow N(mu = 509, sigma = 70) in points. Find the probability that a randomly chosen value is less than 635 points. Use the standard normal CDF Phi and round to 4 decimal places.
